I must to learn both, natural photos and studio, - and the latest stuff is my second time of shooting in studio. It's not about just the composition, but about setting the light the right way (and there are 5 sources of light - in general)...... And to tell you the truth - on the second and third photo she wasn't posing for me, but for another photographer, I just cought the moment. On the second one - she didn't know I was shooting, she was looking straightly into another camera.
