Title: I Was Wondering...
Source: Sketchbook
Background: The moment I heard that Portal 2 was coming out, I had a nerd-gasm and sketched the first thing that came to mind. Of course you have to consider that GLaDOS would be core-less this time around and without those eye-like cores she looked like she had no eyes.
Trying to convey a character with two eyes is hard enough, but four eyes was insane...and perfect for her. Later, I found out that the white pod is actually a central core...which means she has five eyes. This was a great exercise in feature placement.
