I agree with Lorielle99. The gun is cut off, his hat is cut off. You are kinda teased with part of his face. I think if at leats one eye was in the shot, it could add something to it.
The rest though are cool. I like the first the best although his shoe could be cropped out. I think the one where he's "shooting" is nice too, but it looks like the focus is on his knee.
