You've got quite a uniform style. I can look at any of these pics and recognise that they're all made by the same person.
The most recent one, "Anna," looks the best of all of them, to be quite honest. And no, not because of bewbage . Rather, she looks the best because the lighting makes sense, and it's almost uniform. The only point I can make where it doesn't is in the hair.
