The first one is not great. the angle is awkward and does give the effect that the wall is falling on her. The composition is just not there either. you cut off her left hand and right fingers, which is a big no-no, and left way too much empty space above her head. The 2nd one is much better, but would like to see the top of her head (however that does not kill it for me, just a personal preference) and perhaps a touch more in post processing to make her eyes and hair pop a bit more.
Edit: just looked at your sets on Vimeo...You are pretty close, and you have what could be some great shots...you just have a bad habbit of cutting off hands, fingers, feet and toes. Also, it you are going to take a shot below the knees, make sure the feet are showing as well. Also, slight angles are ok, but you have a few that are extreme, and just kill the photo.
