There is some sense of motion, she is not static and she is an attractive girl, projecting an image of physical health, movement and even power, or shall I say positive energy. She is quite sexy, just like a beautiful horse. That is what attracts here. But she should be placed in a right context or environment. The composition is incredibly dull. There should be some contrast, balance, juxtaposition, something that makes this photo a really good one. It is just a girl. The girl is great, but she is not enough. Was there, say, an old static man standing or sitting at the door - it would be a different picture. Just my 2p
