Gotta say, I fucking love your art style. It strikes this perfect middle-ground between realism and cartoony. It's so expressive and lively for a single image, and that's the kind of shit I looove. Honestly, I don't have much in the way of suggestions on ways you can improve. Some of the background characters look a little too goofy in my opinion, but that's more of a style thang.

You just keep doing what you're doing and get never stop improving.
