I think your art looks well enough, the anatomy is actually pretty good, which good, good. I checked out your other stuff, I liked the Stevonnie one, but I'm assuming you draw in pencil and then colour digitally? The tones look too good not to be, but what I would suggest is try out ink pens and markers.
There's not much I can really say other than just keep drawing hordes of stuff until your style develops more into something you like, I still have moments when I look at something I drew and think "this looks lame, no one will recognize it and think it was me that drew it." but then I have some tea and the voices subside. But yea just draw more, sorry this isn't very helpfull
