Phillip, pretty model, nice pose, I'm not sure I like the white chair with the white background. Her left elbow is cropped too much for my liking, but all in all a good shot!
Sai, I think the chair looks like this for a couple of reasons. I was walking around her shooting, all the while she was re-positioning herself in the chair. The type of crop may contribute to this look as well. I shot almost all of the images at 35mm [50mm].
The chair is level on the floor. From time to time, I might have kicked the camera a bit.
