puella magi madoka magica

I've been watching Madoka on tv lately and I couldn't help but draw her - she is the cutest! Please excuse the staff - I know it is suppose to be a bow but I wasn't in the mood to deal with drawing a bow -_-

I'm undecided for the background.... do you think I should leave it plain or go back and add something? If I do end up adding a background I was thinking of making it blue since it contrasts with the pink nicely. Maybe a sky with clouds...? I dunno help me out guys!
