I must say i much prefered the brown hair, green eyes and green bg. That sort of pink and blue together with an elf thingey makes me wince for some reason.
I think the character is very well drawn. The secondary highlight doesn't work atall in my eyes, it messes up the nose and makes her face seem very flat, since you've only lightened a thin area, also highlighting the jaggyness of the outlines.
Perhaps you could darken the darkest skin tone etc slightly, or add the darker tone for the shadows in certain places like under her chin and hair.
Lalala that's all i got.
