Something about the processing of the background throws me off; would have liked to not have the branches on the right sticking into the frame.
With that said, I like the indication of a breeze with the scarf(?) blowing. Lovely model and impish pose; maybe not an imp, but a pixie... Overall has a fantasy feel to the image.
I absolutely love IR photography, but this is a rare instance where I don't think it served the subject well. I find the yellowy background distracts from the beautifully white, well-lit model. She almost disappears into the background since there's no color or contrast to separate her from it.
