I've never done an underwater picture before and, in fact, have been contemplating my first. I think this really impressive - not just for a first time out. Three comments: 1) the foreshortening on her right forearm and the color difference between it and the upper arm are a bit distracting, and a pose shift might help 2) the right collar-shoulder is a bit too twisted for my taste, again a shift in pose might help and 3) the bottom right-side edges of her top might be more interesting if they showed some effect from being in the water - a bit of floating up at the edges might be nice whether done in post or with a magnet. Along those lines, her ponytail might spread a bit too. Very nice, Mark
