I used this idea myself for this challenge myself. It looks very noisy though and the colors are kind of flat. I hope you don't mind but I took this picture and ran it through some photo editors and it made a huge difference. Let me know if you'd like to see the end result.
Much too washed out. Perhaps check to make sure that your monitor is calibrated properly.
I'd go as far to say you would have scored drastically higher because it's a great idea, had it been executed better.
You've done really well to catch the reflection so well here (and the model is a very good lookalike), but the pic is extremely grainy - what happened?
