Hiya! Well, I checked out all the pages you've uploaded and I've got some suggestions for you! First off, hobbyist or no, you're conveying your story through art so, don't feel down on yourself for the things that you don't know art-wise yet, and don't feel like this doesn't make you an artist. You're an artist that's evolving as you go just like any other; everything comes in time and you're doing just fine.
Second, I know you were migrating things over. I did this when I first joined Tapas too so, hahah don't worry about it with regards to what's already made. Just make friends with the scheduling tool for your next uploads. If you make enough, you could upload twice (or more daring) three times a week, or once a week after you get your archive moved over. That's entirely up to you!
With regards to your comic: it's actually quite charming. Al and April play off each other in a fun non-contentious way and that's refreshing to see. They rib each other, they have a laugh, and their relationship seems believable. All in all you've got an upbeat tone and it makes it easy to read right through the whole comic. What you have in the writing department is light, fun, and it's easy to digest tone fits well with the art style because it's light so, that's a good thing!
In the art department, you said yourself you're just learning and you're weren't a trained artist to start out. This is okay! The best part of this is, you can take what you learn anywhere from here! Whether it's adding color, or backgrounds to panels (since generally the main character's don't have a background, the gag with Al running past everybody to the bed would've been funnier if we had a panel of him running past his couch and video games as well, just to show how desperately tired he was and how many barriers he had to pass. It would also help us, the audience, get familiar with his house. Personally I thought he was gonna run past April and Horatio and plop himself in front of the TV, controller in hand so that's a suggestion just for further establishing a joke or environment as you go) there's a lot you can do with adding little touches.
One small touch you might try out first, before getting into complicated stuff, maybe try a little shading on the characters to start. It will make them pop and feel like they're coming up from the background. Everything is a little flat so I feel some of the jokes that could really pack a punch with regards to background gags (such as the coffee truck and the building it's in front of would be more noticeable, on first glance, as separate objects.) Adding little shades here and there (like I said, maybe start doing this with your characters and objects they interact with, like the couch or the bed) can make all the difference. It also helps to attract the eye to an object in the scene which, since you want people to read your comic, sometimes when browsing a site, having an object catch your attention because it pops, can encourage a potential reader to take a look. It also might help to darken the panels that take place at night so they stand out and we, the audience, understand that it's night-time. It helps create a little bit of atmosphere and it's a simple addition that can make a world of difference look-wise.
Color also attracts the eye but, with the style you're using you don't really have need of a lot of color, just make what's there stand out like you've done with other panels and you should be good. On those panels that you did use color, those stood out because it was out of the ordinary so, that little detail could work in your favor. Ultimately it just comes down to playing with ideas and since you're in the best position to do that, have fun! You've got plenty of time to improve your work with whatever you want to add to it. Now, I DO have some resources for you, just a couple, for whenever you have the time to look. Here's one about figure drawing for cartoons, in case you're ever interested in playing with your art style (when you feel comfortable enough to do so). The next is a basic tip about shading. I know it's technically for photoshop but the technique itself could really be applied anywhere. If nothing else, it makes for a good primer.
All in all, you're not doing anything wrong. You've actually got a good start, things just take time and building up an audience is just one of those things, particularly on comic websites. Your best bet is just to keep sharing! And hey, reach out in the forums if you ever have other questions in future, participate in threads if and when you've got some time and if you feel like it, meet people, make friends, it all makes a difference and, on the whole, can help you grow. I hope that the resources I've given you help you out, and I wish you luck as you enjoy your hobby and hopefully our community! Hahaha! You're doin' great.
