It's got a few flaws.
1. Your render, by the hair, its got a white space on it or something? If it is the render than its not rendered well.
2. The pink light on the left can be toned down just a bit.
3. The smudge on the right side of the render looks kind of empty.
4. On your render you can somewhat spot the white "light" on it. It doesn't look good in my eyes.
5. Render could be a little smaller to show the background.
But still its really nice.
