What's great about your comic is it's funny, relatable and your art is very consistent. It's hard to say what to do now. Your style is unique and that makes it stand out in a good way. The way you use space is good, too. I'm not sure if adding more detailed backgrounds would help or take away from the main focus which is your MCs. I think it's inviting to read and it's just going to take time to build a reader base as community comics tend to not get much exposure on the app. I think as long as you keep a regular schedule for uploads people will find your comic and read it.
