Was it worth it?

Decided to have a go at drawing a concept for Portal 1 GLaDOS. I Tried to give her a slightly more insane look, and the cores are fixed right by her head for maximum annoyance (She is in her chair, btw, which is what the cores are attached to, I just got lazy). She is also more restricted by the strap things that hold her in the chair. :>

This one's quite old, actually, I just didn't get round to uploading it. ^^'' I know her shoulders are off... shoulders are always something I have trouble drawing. Along with necks, and men. XD

Anyway, I hope you like this! It's done with markers, if anyone was wondering. And you know the drill, download for fullview. c:
