hey i think this looks pretty sweet, here are the things that jump out at me as a little bit off:
1 - the, i assume its a double-barreled shotgun? The perspective on it is REALLY extreme, and seems more like a copout than an artistic choice. Also, he's holding it one-handed, and does not appear to be a bodybuilder (or Ash), which is kind of a dangerous thing to do.
2 - his eyes aren't looking at us, or his gun, or his match, which would be the 3 things I'd assume he'd be looking at. As it is it looks like maybe he just saw a mustard spot on his sleeve or something?
3 - index finger looks chopped off, i think mainly because it is at a slightly different angle than the other fingers - if it was tilted down just a smidge, so we could see the remaining finger joints (even if its just a pixel or two wide) I think it would sell that a lot better.
Nice start, and cool lighting!
