This drawing I am particularly proud of because it was done purely by imagination. No reference pictures whatsoever. Which means it took a buttload of hours to draw, especially cuz I'm indecisive about composition and poses. But I did have to erase a billion times over the drawing, now in one of my old sketchbooks somewhere in storage. (complete with eraser burnmarks!)
BTW, this was done with a mouse 3 yrs. ago during my pre-Wacom days. And yes, massive carpal tunnel ensued (>_<)
