Wow, this is great, Vim.
It gives me vibes of both Manhunt and Hotline Miami.
I really like the colors and the lines are crisp as always, not to mention the typography is sick.
The only criticism I really have (and this is coming from someone who views a lot of art, not someone who is an artist) is the simple background. It'd just I think feel a bit more alive if there was a grimy street or ally he was standing in, matching the tone of every other part of it the drawing, maybe a few neon signs...
But that's subjective, and judging from what this art has, not what it doesn't, this is very, very good.
