That is quite awesome! Well, even if it was out of your comfort zone, you totally rocked it! I'm curious, how many preliminary sketches did you have to do, to finally get you this great drawing? Or was it more just slowing down and really thinking of what you are drawing, while you were drawing it?
You're definitely broadening your abilities, Tom. I remember when I read your book that you didn't excel at monsters and robots very well, but you've definately come on since then! Well done, and keep at it.
