It's Jeselle on the roof of the bar in Dalaran. I landad, and found myself knee-deep in plygons. I then decided to sit, and the end result is that only her head is visible (and the very top of her right shoulder). It's not hard to see the head, as it's dead-centre of the image (she has pigtails, so I guess on some screens it looks like less of a head, and more something odd).
