I guess it's a style-issue; Either you don't like it, or, like me, you love it!
Cartoony characters are my thing, and I can really dig the look of your drawings. That said...
Backgrounds, backgrounds, backgrounds.. You need them if you want to grow up to be a strong man like me. Your hatchings help, but the odd carpet, couch, wallflower, a line to divide the floor from the walls... anything to bring more life to your comic and make it feel like your characters inhabit a living, breathing world would be mucho appreciated.
Also, posing and camera-angles.. I can't help noticing all your characters / drawings are posed facing left, right, and in 2/3rds shots ; Where's the full face-on? Where's the zoom in, zoom out, birds-eye, frogs-eye view? Experiment with your panels, right now you are suffering from the "talking heads syndrome" (see below)
Try something like this instead:
They are still "talking heads", but we now have a background, moving of camera (zoom in, zoom out) and movement / "acting" from the characters. Much more interesting to read at once
