Hard to tell, it's not at native resolution so I can't really look at it at a 1:1 scale.
As for posing, having him tilt the gun off to the side to create a more readable silhouette could help.
I'm sure there's plenty of pistol reload animations to look at across various media for inspiration, but Resident Evil 4 in particular did some pretty snazzy reload animations, it's 3rd-person modelwork yeah but there's a lot of similar animation ideas there to what I'm trying to get across
note how they pose him so his gun's off to the right of him so you can focus more on it when he does said snazzy animation:

EDIT: As for the actual edit, yeah the lighting does help a lot! Keep at it!
