Being a dancer and fan of photographing dancing, I know how hard it can be to get a good shot of folks on the floor! This is nicely done, shame her eyes are closed!
what a moment you captured here! hope you're getting some good comments and suggestions, and this you're not getting overlooked in this monster challenge. one suggestion i'd make would be to select all the background and burn it out, leaving nothing by your subject to focus on. you might also consider burning out some of the highlights on the subjects' heads. you've got a great starting point, and with some effort, look to be setting yourself up for a great year! good luck!
right in middle of the action. Good shot. Did they survive :)
the headless ppl in the BG are kinda annoying, but hard to crop out and cloning them out would be illegal, so stay they must.
