Profoundly unflattering angle of view and angle of light, light very harsh. There are conventions here, and the conventions are to place the camera level with the face or a little above, and the light both softened and somewhat above, so this photograph violates basically all the conventions of portrait photography. The colors are sort of popped a little as well, which is also a bit unflattering.
Does it work? Well. There's a slight horror-movie feel from the harsh, low, light. That makes it a little unsettling, which isn't a bad thing, per se.
The unsettling lighting doesn't seem to be working with the other elements, though. It's just some dude in a baseball cap looking like a dork standing against a wall. If you looked scared or scary or angry or.. anything much.. this might work better.
The shadows are kind of cool, which might be what you were going for? "Sort of cool" doesn't make for much of a photograph, though.
Think about what you were going for here, and think through how you can bring that out better. You might be on to something here, you might not, but if you are you haven't got enough stuff pulling together to make it work.
