Very good work! Her proportions and pose are well executed, I am particularly impressed with how you've done the multicolor glow. I assume you duplicated your color layers and blurred them behind your main picture? I'd never thought to do something like that, very neat. If anything I'd recommend you make her face a little more slender, and she seems to have a slight under bite, but that aside this is something you should be very proud of! Keep it up, and thanks for sharing :)
