She does have clips in her hair, I guess they're masked by the red splat
You're the second person to comment on her waist and belly area. I really didn't do anything to her figure beyond a few minor tweaks. I wonder if her twisting her body to the side like that and then cropping her off at the thighs makes it difficult to interpret what her pose is?
Yeah... but the real Asuka isn't real, she's a cartoon representation of a 14 year old I was working with a model and I didn't really feel like making her too terribly much smaller than she really was. But you are correct, Asuka was much thinner.
