I want to thank everyone for the comments.
The mannequin shot was pure luck. I happened across the scene as people were moving the mannequins indoors. I spied the shot I wanted and right before I hit the shutter button, I spotted the doll at the bottom, and quickly framed the photo to include as much of it in the shot as I could. It was a tight fit, as I was backed up as far as I could get. I got off one shot right before a guy picked up the main mannequin and started moving her indoors.
The band was shot outdoors after the sun went down, under heavy stage lighting.
Once again, thanks for the comments.
