I was doing some quick sketches at work today, and the last one I did turned into this several hours later. I wanted to do a big hulking mech, sort of a Sci Fi Big Daddy kind of thing. I was also thinking about sci fi anime like Macross and such. Part way through I got to joking about this being a direct descendant of an artificially aware Honda ASIMO, hence the honda logo.
Done completely in Photoshop CS4 on a Cintiq.
