yeah what is with the rock, also there is not much detail, but well done

What is that giant rock doing there on the floor? That may be a mimic, so watch out.

I agree, I could have made her more sexy, but I guess I didn't want to push the limits of inappropriateness.  Maybe I should have. 

Thanks for the tip about the shading on the abdomen.  I can fix that a little, but she's kind of pulling away from the wall and causing her to twist just a little.

I agree about the pose, it's nothing sexy. And the shading of abdomen makes she looks pregnant.

Maybe making her bikini smaller would be better.

The point of this pose is to be somewhat uncomfortable and unnatural. 

ref gives much more than right anatomy (eg. sexy pose rather than ghoulish pose) you should use one/many in future.

No reference was used with this.  I few looks at my own hands was all I used for the hands.  Her left hand I couldn't get quite right, but I didn't want to mirror the right.

ref would help especially with hands
