Canvas looks too big for the stock, and something about the texture looks low quality, maybe try a different smudging technique. Also, stock placement is boring, and the border is unnecessary. All in all it looks pretty generic to me, try inventing a new style through experimentation.
Well, I wouldn't be that harsh. lol It looks nice. Yeah, it's nothing new, but nonetheless, it's nice. The B&W looks best to me. Lighting flows good with the stock. Good work.
