Hmm, with the first I like the lighting but the focus doesn't really work for me. I'd prefer either her whole body in focus, or something particular sharp with the rest not. It strikes me as a "good idea" shot, maybe play with it a bit more.
The second seems blown to me - too high key. But I know other people like that effect much more than I do. your call
The third one works for me. I like the clean shapes and contrast between the clock and
model. Perhaps a touch less hip-swing but that's very subjective - the muscles on her left side don't quite fit but I'm not sure how I'd direct the
model to improve it.
One question from me... how do you deal with bruised
models? I have a friend wanting photos but her wonderful clear skin shows every blemish really clearly, so she always has dark blotches from bumping thing (suggesting she spend a month not doing anything is not one of the options).
