Kinda cool. Lighting shot from back is better than the front shot. The big guns like that actual detract from the character. A big Magnum 6 shooter might make it work, but it would stil be better as sorta small in his hand. The other hand should have a large custom made brass knuckle, hahahah. It’s just about balance. The character is quite well done, I like your stylization on the mesh. The wrist doodads gotta go.
Might I suggest the back shot, twist the body around a bit leave feet with a little knee flex and bring the head around as well and more than torso. This would give you a slight motion pose and convey some of his mass, catch the light and if the face had even a little expression and head titled a little to a side, would punch this up several notches. I’ll leave you to the details if this makes sense for you, but statue presentation that is utilized by so many just leaves so much out from the hard work done, especially on this character.
