C&C on local band promo pictures

I recently did a photo shoot for a local outlaw country band. These photos will be used in a promo pack that will go to potential venues and booking agents. Thanks

I'm not loving the background above them in the last one, but they look pretty good to me.

There's a spacing issue to me with the total group shots. Everyone crammed together and so much empty space on the sides. There is enough room so that you aren't only getting a sliver of someone's head. Fill the frame and you'll have more room for each individual.

The contrast is a bit low as there are no true whites in them and in the first shot is all pretty gray. Too many faces blocked in the big group shot as well. Same goes for the last shot. In the last shot are the two guys down front that much more important than the other band members? Using a wide or ultra wide and shooting low emphasizes them at the expense of the other people in the shot.

I like the second photo the best. It seems to put the band members up front and shows who they are. I would also suggest that the heavier set young lady tone back her make-up a bit when you plan on shooting. She looks like her make-up if caked on while the other three young ladies looks much more natural.
The last shot might have been better if you were able to shoot a little higher and not get the busy background in the mix.

Thank you for everyone's input on the photos. It definitely will help me improve in the future.

I like the IDEA of the last shot the best...
Just need better spacing and background.
