MV study girl

I should be sleeping but I had to sketch this out once I saw it on a Music Video.

The rough is done. Youtube made it little choppier than it actually is.
I'll clean it up like below image bit by bit.

update: Here is a link to the said video: http://www.youtube.com/watch?v=DQ1hvB_L30o&feature

Perhaps I've exaggerated the head movement too much. It distracts from the hip. which is the real focus.
