Tajinder,
I keep coming back to this shot. You have captured their character and personality. I like the grain/texture in their hats and clothing and the profile view.
*I'd clone out a few of the larger white dots on the sleeve. Also, I'd meter on the skin to show off the detail in that great beard.
I like this shot, Tajinder. I like the mirrored poses of the two gents - even to the similar eyeglass style. Too bad the gun barrels weren't more parallel, but that's a minor point. Nicely done!
