Alright, here is the jig. I just tried vectoring for the first time ever and I want to make a wallpaper with it so that I could submit it here. BUT I have run out of ideas and whatnot and I would delight in any tips the expert wallers at AP might have for me. The more I look at it the more the more I feel as if I should scrap the whole deal, is this a wise decision?
Wallpaper (small version)
Here is the original image I vectored from.

Mmm, kinda too simple
the chest need some contrast, the shadows are barely seen. altough eyes and mouth are the inverse. try lowering its opacity a bit, will work

and dont abuse textures

Too bright. hurts my eyes the moment i saw this. make it a bit darker. design is too simple. put more boarders on the girl.

I like it a lot, it's simple and original.
But I agree that you should darken it at least a little bit. After all people will want to place it on their desktops and you don't want them to have headaches later, right ;)
