Hi Nicolas
Out of these shots of Natascha I prefer the 3rd, I like the pose, composition, everything about it, very sensual, but there again the 2nd is very alluring too....
I'm not too sure about the 1st one. She is exceptionally beautiful, you're very lucky to have her as a model....
You certainly have been working hard, and it shows - well done! and thank you for showing us all of these.
