The left eye needs more shadowing. >___>

Her beautiful and cold face is always drawing ironic feeling like Janus. Red colors look like blood are always her good company.

It's much too simple.. and frankly, large.

It screams for text and words, words to clarify the meaning of this wall. It doesn't have enough going on in it for my taste, and the fact that her face is so large in here really dilutes the evilness you try to show. The fact that one pupil is bigger than the other doesn't help much either.

As a vector, it's absolutely gorgeous, apart from one pupil being larger than the other. As a wall it doesn't work much at all.

I think if you worked on it some more, it could be much much better and plausible. I think it either needs more heat, or more coldness. Here... it's almost neutral.
