Good shots.
The second one is my favourite. Good composition with great expression.
I would crop the black space behind the singer on the first photo. The singer has small white spot under his lips, easy to retouch.
Brilliant first shot Frank, perfectly captured and absolutely love it. Can’t actually see any way of improving it. It looks to me as though the ‘white spot’ Roberto is referring to is actually a piercing. Nice exposure on the second shot to keep the detail in a white shirt, though a slight pity to have cut off part of the left arm and the headstock of the bass. Both good shots though and like them a lot. 8)
