Pose shamelessly copied from this. I was like, "I like this, but the face looks kind of weird. Also, not naked enough."
On the original:
Face looks wierd, I agree.
Ass is a spear
Yours:
Shading around her nipple should be smoother. It looks like a sticker =/
Also, since you do line weighting, you can try softening the lines in that area. It really stands out, and it doesn't look all that appealing...
The shading on the rest of her body doesn't match the one in her hair. It looks unfinished.
Other than that, Reisen is fine. She has a huge smile on her face <3
And that's one hell of a curve you gave her torso~
She must work out!
