Attitude 01

This has a nice palette and sense of movement. I always say that placing people off center only works if there's something in the empty space to balance it out. What you have here is a lot of empty white space on the right. Contrary to what people say, it's ok to center your subject. More subjectively, and I know you can't just go an "do over," I'd like to see her arms extended more directly to the sides rather than angled into the background. They look a little out of proportion to me because of the foreshortening. Keep at it. Every photograph ever taken can be improved.
