I wasn't familiar with either 'Sing For Me' or Yellowcard. That is what is so great about this challenge. I have just Googled it and watched the video, and I'm glad I saw/heard it. I love your picture too.

I believe this is mike_311, at least it looks like his wife from other shoots. This is the best photo of the challenge. It really helps that the subjects hair gives the perfect contrast to the high key whites of the rest of the image. Hopefully you're not getting dinged for having OOF instead for the upper right hand portion of the image.
Sing for Me - Yellowcard
Very lovely, both the model and the portrait and treatment. I would have liked to see more detail in the eyes but don't know how you would accomplish that without selective editing - I really wanted to bring back some areas of my own and couldn't in basic. Voted earlier.
Yellowcard. Interesting angle, which renders her eyes a little odd-looking, as they are looking up and make the whites look strange. But the lighting is really lovely.
