It's hard to like........ discern "style" from a single image, I think!!
Younger artists often tend to think of style as things like "drawing eyes a certain way," but actually style is a lot more than that; it's the shortcuts to drawing you've picked up that play to your strengths, the sorts of compositions that appeal to you, the way you put colours together, the unique combination of things that are comfortable and solidified for you.
What constitutes "style" in an image? Is it the way you draw eyes, or the way you draw clothing folds? No, that can't be true -- if I drew eyes differently in a few drawings, those drawings would still be in "my style." If I draw characters with different proportions, they're still "my style."
It's also hard to tell because I think of "generic" drawings as being when like.... there's nothing interesting or different about the different elements. Like someone who just learned to draw faces from studying a single anime face and don't know how to reach outside of that. When you draw a tree, is it gonna be a Generic Cartoon Tree from memory, or are you gonna look up pictures of trees and how other artists handle trees and put it together and figure out the best way to draw trees for you? Are you able to draw characters with different faces and different bodies and different noses, or do they all look the same because that's the only Generic Face you've learned to draw? That sort of thing.
That said, I think the best way to work on your style is to.... not focus on style specifically, and focus instead on how to make your art better and better!! Look at real things, look at how other artists draw things, and don't be afraid to copy and experiment and try different things. If you're scared to incorporate new ways of drawing things into your work because you want to keep A Distinctive Style, then ironically that's when your style stagnates and becomes Generic because it can't grow.
