Thanks for the comments. I actually wanted her head tilted back like that but I see how it does seem off, maybe if she was looking up instead of at the camera and we saw only her profile it would have worked better. Also yeah it needs more light on the face. As for the thing in the second photo (I think it's a door), it's been driving me crazy too. It's the wall of a demolished barn and there was junk everywhere around it.
I think one of my biggest problems is rushing, the models (friends) did this as a favor to me and it was so cold out that I didn't want to keep them too long. I think sometimes I need to worry a little less about the comfort of others and focus more on getting the shot, but it's hard when you are working with people you know and care about.
