CM : Fly me to vanilla sky

It is truly beautiful, one thing I might add is perspective.

The eye level is at her buttocks, yet It's like I'm looking up at her legs.

my question is where is the vanishing point.

where the stocking starts on the leg has me confused as opposed to the rest of the body. put your hand on this picture and block the legs, I know it has an intended dynamic effect but the legs do not agree with the axis of the upper body. It's like legs(in 3d terminology) are created on a slightly oblique plane.

But otherwise it's an awesome picture.
