This was from a sketch I did after watching the classic Nick Cage flick. Apparently, GR can just hop on any thing with wheels or maybe it's any mode of transportation and it turns into a sweet flaming ride.
I started working on a cintiq at work and it's made me realize just how awesome it can be to sketch digitally. So I'm going to get one for personal work very soon. Here's a couple of sketches, I've been in a fantasy barbarian mood lately.
