The Freaky

The background of the picture is very good and fits with the overall theme of the picture, also the shadow is a very good copy of the original. Also you've managed to get the light source and all relevant shadings and shadows matched up with that very well.

However the drawing of the girl has multiple problems with it.

Firstly the hips are way too large for the size of her shoulders, and waist. Normally the waist, shoulders and hips are in proportion with each other, the shoulders normally being ever so slightly smaller than the hips.

Secondly her legs are way too big, she looks to be ultimately skinny but the legs look gigantic on her.

Thirdly the hair doesn't look real, it should have more flow to it and be more separated not appear to be so clumped together and blocky.

Lastly the face is wrong, even if she does have yellow eyes there should be a slight colour difference between the pupil and the rest of the eye, even if it's only a slightly darker yellow. And the eyes are ever so slightly too big for her face.

Otherwise the drawing is very good.
