Alright, I'll have a go.
I'm not subscribed to your comic, and I don't read it regularly, so take this as a complete outsider's view.
Initial impressions:
1.) You have a bunch of spelling mistakes throughout your comic. I think you need to either proof-read better, or get someone to proof-read it for you. Spelling mistakes don't make or break a comic, but they certainly don't make a good first impression.
2.) Your art looks stiff a lot of the time. Both because the hand-drawn characters look out of place against the 3D-rendered background, but also because the characters themselves have kind of stiff expressions. For example: when Captain Flock yells in anger on page 6, his expression doesn't read as angry. In fact, he looks kind of bored. If you want his expression to read as anger, you need to angle his eyebrows down - the way they're drawn right now looks relaxed, not tense/angry.
Now, on to the actual storytelling.
1. Lack of focus.
I'm honestly not quite sure what sort of story you're telling. On the one hand, the setup in the first episode seems to be leading to some sort of critique of society regarding high crime rates and methods of punishment - but then the rest of the comic seems to focus a lot on getting people (mostly women) into states of undress so they can be spanked.
There's the crime-and-punishment angle running parallell to the spanking-and-nudity angle, and as I scroll through the pages, I feel as though I'm perpetually stuck in the setup to a porno that never quite gets to the point. That fact is working against it. Using those sort of cues (frequent use of spanking of partially dressed women, lots of pages with almost full frontal nudity, etc.) without delivering on them leaves those readers who do read your comic for that aspect of it perpetually disappointed.
When you do focus on the crime-and-punishment angle, it keeps being derailed by scenes depicting these cues telling the readers that you're building up to a fetishised sex-scene, so those readers who are reading for the crime-and-punishment angle are perpetually distracted by that.
2.) Lightweight conflicts.
Your comic feels unfocused, and part of that is how you handle the progression of your story. There's a lightweight aspect to the way it unfolds - Lawson's reaction to Lorraine being a criminal feels strangely easy; as if it's as if it's all in a day's work to arrest your wife. Lance's blackmailing of Cassie into making out with him in the bathroom is also weirdly easy - especially since the thing he's threatening her with his a photo of spanking. The reader has, up until that point, been led to believe that spanking isn't just accepted, but very commonplace in Swipe City. Logically, that photo wouldn't be too much of a scandal.
Everything just sort of keeps rolling along. It doesn't feel as though the protagonists (I'm assuming the protagonists are Lawson and Cassie, at this point) have all that many moments of doubt or moral quandaries or anything that they have to get through. even when they do run into trouble - like Cassie being blackmailed by Lance - she seems to resolve it and shrug it off almost the moment it's out of frame.
It feels like a daytime soap opera, and not in the best of ways.
(also, sidenote: your main conflict revolves around dead prostitutes, and unfortunately, it feels as though you've picked prostitutes to give yourself an excuse to draw half-naked women, rather than to say something about how crimes against sex-trade workers are easier to cover up or get away with. If you did pick prostitutes because you wanted to draw half-naked women, that's, er, kind of tasteless. Especially since you're also depicting a lot of brutal violence that is mostly, if not exclusively, aimed towards those women.)
3.) How your characters are perceived.
You said your readers have told you that your characters are "not nice people" - and I have to agree. Out of all of them, I think only Cassie - and possibly Captain Flock at this point - make out as positive. All of the others are some manner of bad.
Lorraine is clearly terrible - using a disturbed mental patient with anger-issues to literally murder people - and Lawson is a cheater, which is not nearly as bad as his wife, but still counts against him, especially since he knowingly carried on the affair with a prostitute, and enabled it by (at least so I interpeted it?) giving her a job in his home.
Jenny is, and I hate to use this term, a stereotypical bitch, who is not only mean and horrible towards Cassie and Lawson's son, but also clearly uses sex (or promises thereof) to manipulate people - which is a classic way to depict a woman's bitchiness which is clichéd and honestly kind of boring at this point. Lance is horrible as well, using blackmail to get sexual favours and - even after a brief moment of positive action in saving Jenny - leaves the scene NOT thinking "Wow, good thing I managed to rescue this person!" but instead "Woohoo, boobs!". I realise he's a 15 year old boy, but if you want your readers to have a positive impression of him, you're going to have to give him more than one moment of heroism.
And you said here that you feel sorry for Clarence Potts. Please be aware that most of your readers will most likely NOT feel that way. Yes, he had a terrible childhood and was traumatised by his step-dad - but in the present day world of your comic, he beats women to death. It doesn't matter what manner of mental disorder he has to explain that behaviour - he's a serial killer. I don't know if you intend to try to make him a more positive character in season two, but I doubt if you'd be able to pull it off.
4.) The contrast between your world and ours.
The laws and legal system of your world is clearly different from the one we're living in in the real world, and your characters are clearly used to it. But your readers are not. We are all going to use our own experiences of the world to interpret yours. So even if we can consciously acknowledge that the rules are different, our visceral reaction is going to be based on our moral systems.
For example - if I had stumbled on your comic randomly, instead of through this topic, I would have noped out of there before I was finished reading page two. I'm Swedish, and in Sweden, it is illegal to spank your children as a method of discipline. Because this is what I'm used to - i.e: spanking children = bad - I'm going to react accordingly. It doesn't matter that in your world, that sort of thing is accepted and okay - for me, it's very much not, and I don't feel comfortable reading about it.
This reaction isn't something you can do much about, but it can be worth keeping in mind when asking yourself why the reception of your comic is the way it is.
