I love the caught in the moment 'action' shots. You have a sense of setup and pose for your models, taking their amateurishness and bringing out their potential--what they could be. Giving me a sense of "I should be there as a witness." I'm also glad you used color on this one...it would not serve as well nor send any message lost in a black and white.
This was preparations for the photo shoot yet to come, so it's really more a matter of seizing the moment as I went by rather than of planning any pose .. : -)
The colour versus black and white is an interesting comment too. Very often I feel that colour is a distraction, bringing elements into consideration which detract from the message. It varies tremendously of course from scene to scene.
