Must admit, not a fan of any of them.
IMO, you should all adopt a common stylistic theme dresswise. All to disparate, your intended musical style is ambiguous.
As said above, drop the instruments, mics and stick.....dreadful.
Stick with either natural surroundings or no surroundings at all, possible on a solid dark colour background.
Try just head/shoulder shots of each band member, but avoid "straight at the camera" poses. Something quite off the wall perhaps???
Photo shoots are hard. Its easier for us, as youve guessed, to advise you what NOT to do, rather than the converse.
