I agree, I think they look better in color. The only one that's working for me is #6, but I think you could crop it much tighter? (I did this quick in MS Paint, so getting rid of the ref's arm in the top left would be helpful.)
Also, maybe brighten the guy's face a little? The one that's getting strangled with the rope?
Thanks for all the responses. I appreciate them all. Let me explain my thought process behind the black and white.
These are people that performed in 9 shows that week, all of which were county fairs. It's a grind, it's difficult work for, frankly, very little money.
I wanted to express that with grittiness in b/w photos.
