I agree, they look pretty darn good. Crisp, well exposed, good color, etc!All three of those photos look technically pretty good. Maybe a bit more of a look at the face of the musicians would be good, but exposure wise all three shots look good. Focus looks good. Shots look sharp. Your vantage points look okay on all three shots. I see a lot of improvement in these results compared with what you were turning in a month ago!
