Six hours of Spacebird

I only realised after having finished it that the spaceman's shadow has Batman's head. This is fine with me, because I love Batman.
So, I've had this Spacebird idea for a really long time. I must've sketched it out a dozen times or more until I found the right one. Six hours of drawing later and we have ourselves a winner.

Super-proud of this one. Click to embiggen, as usual.
