Window Light Portrait

I chose these pictures because of the proportions and the way the light falls on the model's face and body creating smooth shadows that compliment the overall picture. 

I definitely need to learn to use my camera properly as i did not quite know what i was doing. I was focusing more on proportions and think that it turned out pretty well in the end.

What i used to get these pictures?
