Salutations! Okay I read through the whole thing so I could give you some feedback and I hope it's helpful. I'll start by directly answering the questions you asked and expounding.
1. Before reading, does it look like something you'd enjoy?
I will say that, before reading if I was just glancing at it, (based on art and only art alone) I probably wouldn't click on it. Now this is not your fault, it's just not an art style that immediately catches me. I'll say again: This is not your fault and don't change your style based on this. It's a personal preference for what catches my eye immediately.
2. What do you think about the art style?
While it's not something that I'd immediately click on, I think your art has merit. You're good at establishing a scene and your characters are so distinct I can actually recognize each one immediately without having the character soup problem, even though you've introduced a wide cast. This is a good thing and though some characters have faces that are shaped very similarly, I can tell them apart because you've made their color schemes different or given them a unique feature. This is awesome and I'm glad to run into a comic that has done this.
I will say that the art is very stiff, though. I don't feel the natural movement of a character, they feel very rigid or puppet rigged. Everyone is standing or sitting in a pose that looks uncomfortable because, again, somewhere we've lost natural movement. I'd suggest some figure drawing to improve this issue. Even if you're cartooning, trust me, figure drawing would bolster your host of skills like mad. I do enjoy your visual gags (such as the Batman/Superman characters and their respective parodies coming to life). Again, I think making your characters more fluid and less rigid would help make them feel more like comic book characters and by extension help the comic book parody. Either that, or you could really stylize and make rigidity into an actual visual uniqueness.
This one is hard because when it works, it really works, but when it doesn't it can be a turn off. Some examples of super hero parodies done in a rigid style that worked: Valhallen of The Justice Friends, or to get that dark and gritty look: Invader ZIM, and of course The Powerpuff Girls (Originally known as: The Whoopass Girls). Now, I'm not saying overhaul your style or change your identity at all. These are just examples of line work on rigid characters that worked well and might be helpful in future.
3. What do you think about the story?
The story has a very slow start and, while that isn't always a bad thing, in this case I felt like the character establishment in the slow moments could've been handled better. I was immediately derailed and turned off by the bar scene. I've never been to a bar where coke is called "A Woman's Drink". Not ever. I actually found this off putting because lots of people drink coke so the joke itself doesn't make any sense. Also, usually when someone is at the bar and only drinking coke, it means they're a designated driver. I've been to lots of bars and whenever I order coke with my buddies around, they assume I'm the DD. Granted, I am, but that's the go-to assumption even when I'm alone; they think I'm staying sober to drive someone home. Even other patrons make this assumption so, again, this is why the coke gag makes no sense. I know the guys at the bar are supposed to be jerks but, they're acting like they're 5 and on the playground, not adult bar talk at all.
I've never seen an adult man put up the "L" sign to a stranger, I've never heard two adult men accost someone who is wearing comfortable clothes to a bar by telling him "You need to get your big-boy job" or something like that. The whole scene was weird and I almost stopped reading because it was too juvenile. I know it was supposed to be a "gotcha" moment, how this unassuming man turned out to be their boss, but why not have him overhear these two talking smack on his company practices? Or spreading hurtful gossip? It seems more likely than two adults giggling about "El Oh El, U so Dumb" which is what the exchange felt like.
It also didn't help that the bartender fawned over Knight. I know this is parody but I didn't really buy the bar tenders attitude. It just seemed politely stock, like something out of the imagination of someone who has only ever seen bars on TV and not been in one. Again, I do know this is supposed to be a comedy but, I also want to be honest about the scene so you know how a reader might feel about it. It's one of your openers and part of your hook, so this was my first impression. Once I got past this scene, everything else was miles better. I like that SK was running about the city with his sort of "Heroes Monologue" talking to himself as if he knew the audience was listening, where if you were a person IN the scene this would be insane! It is a fun gag and really highlights how silly older comics were when they did this.
And holy hell, when Jesus and his friend were playing video games and Jesus's phone keeps going off, that was really funny. I could watch these two guys be in movies, watching TV, playing video games, all the while Jesus's annoying app is just going off like mad. This is a fantastic set of comedy. The dialogue between these two is natural, it feels like friends chilling (and I love how Jesus discusses the prayers like a cashier discusses irritating customers, this was a great bit). I actually got really wrapped up in Jesus trying to chill with Lue and get him to stop his monster thing. How they hang out behind God's back and have each others numbers. Though Satan is the villain, this paints them more like Greek Gods in that, they don't actually hate each other but they use humans as a means of a pissing contest and this is fantastic joke territory. I feel like your comedy chops really shine here because this part of the cast had a fantastic introduction that was immediately relatable and funny.
God trying to make humans again but screws it up the first chance he gets? Yeah that was awesome. An Angel Prospect who is going to screw this up on the one actual day God decides to help humanity? It's already funny. I'm glad I hung on reading after that first scene because these scenes were great.
4. Do you like the characters?
Yes and no. I think that SK is a fun Batman parody, but he's very...bland because of it? It feels as though every joke he's going to have is going to only be Batman related so, we're not going to get some of the natural comedy you're good at creating. So far every character plot point with him feels strictly Batman, where he could encompass a wide range of "Dark Heroes" that could expand his repertoire. Technically your comic is in the early stages here so, I'm willing to bet you'll have lots of fun stuff in store so this is really more of an observation.
I didn't think I was going to like him from his first appearance, being that he looks like Hitler, but Lue is pretty funny. He's the beneficiary of AA programs and doesn't drink, he messes around throwing monsters at humanity just to have a pissing contest, he and Jesus BOTH make fun of God for not being involved with humanity, and he turned out to be (ironically) likable. The only thing that really puts me off him is just his resemblance to Hitler. I don't know if that's intentional or not but, it does keep me from fully enjoying the humor. (I just find Hitler jokes to be the easy connection when it comes to Satan or hell. Granted it IS for very good reason, but they're just made too often in every media I can think of and I'm over seeing them.)
God is funny because of how others characterize him, and it's particularly interesting that even Jesus seems to think he's fobbed off the world (while simultaneously ignoring prayers for video games). I think you've got great gag territory here and it'll be interesting to see where it goes. All in all, your characters are funny once the ball gets rolling and they're dialogue is natural once you have them talking to each other in a real way, rather than the sort-of straw-men in the bar scene. I think you're making some fun work and I hope that my feedback has been helpful (and congrats if you made it to the end of this novel!). I wish you luck!
