Digging through some old folders, I found a few more pieces from my time where I designing a lot of Portal 2 fanart.
The first is a quick model sheet I threw together for my design of an android Wheatley. It was mostly for my reference and for anyone else who wanted to draw him.
Since I always love drawing interactions between characters, I also did a quick little paint of Chell and my version of Wheatley taking a breather from testing.
