This was the next big project I did after the portraits. The alien robot guy was inspired by Ultravisitor and album by Squarepusher. If Squrepusher had asked me to design the album cover for him and I'd managed to maintain consciousness long enough to nod "yes," this is what it would have looked like. Also if you haven't heard of Squarepusher and like drum and bass (or just good music in general) I'd recommend you check him out.
I did this after reading some excerpts from Andrew Loomis's Successful Drawing. I was having a lot of trouble coming up with lighting on my own and that book was incredibly helpful. This took about 9 hours and was completely from imagination.
