Edit 8-30: Yes guys, I know, don't look into the operational end of the device.
Chell from Portal 2. I want to draw a neat picture of GLaDOS too, but it's slow going since I'm not used to drawing robots.
Made in Illustrator CS5. I got the Aperture laboratories logo here: [link]
Chell and Portal 2 belong to Valve.
EDIT: Uploaded bigger version. Edit 2: Lessened the shadows on Chell, and I'm much happier with the result.
EDIT 5/23: Properly lessened the opacity of the reflected blue light on Chell. I was wondering though, should it be orange..?EDIT 6/21/2011: Changed the gun color to blue, added in the white of the gun that I forgot, neatened up a few things.
