Graphic for MandaMichalka

Hello Guys :)
I was busy  doing a graphic for a good friend of mine, Manda! (MandaMichalka)

Well, i need some more practise, especially for the Hair. The Sweater isn't my cup of tea either, but i find it difficult, to shade and highlight white clothes. Maybe it was only the sweater this time, maybe it will beeverything white. I hope u like it and at most Manda :)
