The orange, or yellow, whatever it is, draws my eye directly to her arms. A more subtle garment may have helped to keep the focus on her face. Also, the white of her eye looks blue, and her skin is a little pink--perhaps from the saturation.
a nice shot, but the focus is poor, which brings it down. that's realy my only complaint - nice colours, nice composition, nice exposure. is this perhaps due to how you're preparing your images for challenge? look at the tutorial for that if it is - i did and it made a huge difference!
