Shego Ecstasy of plasmafire V1

Again a Shego portrait and again different versions of it, since i have problems in favoring one of them ^^

There is a version in classical "Shego-green", one is more in red and a third one is more in "spooky"-green.

Somehow i'm not really satisfied with all of them.
I think there is something wrong with the shadows/highlights i did, but i could not figure out what's wrong.. strange.. must be my lack of artistic skill. I really learned by creating this pic, that my imagination of reality is far away from reality. It's like my brain compresses things down to a minimal lineart.. -_-

I used a screencap from the Kim Possible series as model for the torso and head outlines (excluding eyes, face, mouth), since i have problems drawing right proportions, but the rest was done by myself

I tried to make the eyes look more wet.. but terribly faild in doing that v_v

Edit:
This is Version 1 (standard "Shego-green")
