This sounds cool!
You have a very nice, simple art style that I think is very charming and works well with the sort of comic you're making. Although I think that you could benefit from some anatomy studies. Even the most simple styles can be improved when they're well proportioned! Obviously there's no shortcut to becoming really good at drawing anything so you'd have to be willing to put in the time to improve. I recommend this website https://line-of-action.com/practice-tools/figure-drawing/ if you want to try and get better with drawing people (it's really cool, it lets you pick the kind of people you want to draw!). Gesture drawings are super helpful when you're trying to improve anatomy/proportions so I highly recommend that you try some out! There's a million tutorials everywhere you could also look for that might be helpful. References are also insanely helpful so if you ever struggle with a pose or something, just look some up! Art-wise, I'd say you're doing pretty well but practicing basic drawing techniques would really benefit you (figure drawing, point perspective, etc.)
Also, though this isn't really that important, I recommend changing the line weight on your panel borders so that they don't match the line art of your drawings. Someone mentioned it already, but messing with line weights would be beneficial. Having a thinner lineweight for the lines inside the form (clothing wrinkles, etc.) and a thicker panel border would show a good variance of line that would be aesthetically pleasing and more interesting to look at. Though these are just suggestions, it's really up to you! Good luck with your comic, it looks nice so far!
