The One to Save the World WIP

This is the piece I'm currently working on. I've just finished the really basic outline for the P-51 Mustang fighter plane.
Next on the to do list, the sexy ace who stands at the foreground, looking proud (or perhaps troubled) in front of her plane.
The final setting is supposed to take place during a post-apocalytpic time when evil robots have taken over the earth, and fighter pilots such as the one I will be drawing in here, is humanity's last hope for survival. Bla bla bla!
