I think as a suggestion for the next time, you may want to zoom in on some moments - some individual interactions between people but also come a little closer. I know it's the first time you're shooting, but use the fact that you're familiar with the people - you don't really have to learn names, places, or familiarize yourself with any lingo - to your advantage. You went to Trevor, you're familiar with the people and the culture. You can engage the dancers in a way when they're not working to make it easier to go up to them and just snap when you are working. Talk to them!! It helps.
You may want to have conversations with them - ah, here, the trappings of documentary photography. Make a lunch date with a choreographer and ask them about their process if that's what you're interested in. You have to get to know the kids outside of this - you don't necessarily have to photograph that process - in order to understand their personal struggles and successes in the dance room. So often dancers are just bodies, right now, your images are basically the antithesis to the normal perception of the dancer: awkward.
which isn't a bad thing at all!
Ok and for technical: Why color?
