It's GLaDOS!Well done, the colors, face, transition, all of it was brilliantly made. If I may make a small suggestion though, I would increase the delay between changes. Maybe 3-4 seconds. Many people coming across this drawing don't realize it's an animation, and it will be MUCH more powerful if they stare at it for several seconds, only for it to suddenly glitch and change to the dark version. Lulling them into a false sense of security, much like what happens with the real GLaDOS. Keep up the great work!
