This is a really lovely piece. I like the lines and motion, and the light in it. The model's expression is a lot of fun. One thing I find detracts from the overall piece is the bra. Although the colour is perfectly matched to the skirt, because it lacks the blue cast that the shadow underneath it have, it stands out in a way that changes the shape of the chest and upper body and makes the region look a little more weird than it should. I don't know if there was an intent to have focus pulled to the chest, but given the nature of the other elements in shot, I'm assuming that wasn't the intent, but it is happening because of the contrast in colours, both in tone and in shade. I like the textures, and the heaviness of the reds colours in what would otherwise be a entirely light and upward motion piece. I also appreciate how and where you've placed your signature.
