My opinion on the hand: The only thing I see wrong is that the fingers should curl more around the handle of the gun. It appears that the gun is being held only by the thumb and tips of the fingers. I just think the shooter should grip the gun more tightly. The angle of the hand and arm are fine to my eye. I can get the same basic pose on my own arm and hand without strain.

This is not my "second childhood". I'm not finished with the first one yet.
