i try to leave a critique for only the art and images that intrigue me or that seem to jump out at me. This image is one of those. although there is a very light background the lighting used seems to really be subtle, the models dark hair and the shadow work makes this even more obvious. The pose, with the arm down in almost complete shadow (apart from the wrist and hand) also lends strength to this dark image, the wetness on the body and the somewhat angled look of the model complete this rather interesting piece, there is also darkness in the top of the image to draw the viewer 'down'
what i dont like? the image could be a little sharper, but without knowing the full details of the shot this is just nitpicking.
Great work, good looking model, great pose and superb and daring lighting. Well done
