I like it a lot but I feel your style is sort of halfway there. I would either streamline it more or go all in with the dark shading and exaggerate this aspect of the picture more. It's very good but try playing with extremes to give it even more personality. Have you ever re-drawn the same image multiple times improving it or do you keep drawing new stuff? Disclamer: i'm no artist so that might be a bad recommendation but worth trying it out no?
I've never properly redrawn the same image, sometimes I'll draw the same kind of things when doodling bits and pieces on the same page, but full pictures like this I tend to draw once and hate forever because of the flaws I can't fix :) I think I understand what you mean about "halfway" on the style, I was trying to stick to clean detailed lines but kind of veered into scrubby rough edges part way through.
