Lol ok I was so breathless i decided I would just critque it XD. I love the pose you chose it really showed of her beuty and grace and allowed you room to work great on her markings. Onto the markings, I know their almost next to immpossible to get right but you did a great job getting them close as you could.
The shading I think looks awsome <3 all in all this is a wonderfully piece that you really should be proud of. Fff it almost looks like a picture acctually XD I was really suprised when I saw it X3
