Whole body plus outfit took prolly 3 weeks on and off. The face and head took prolly 2 weeks cuz I'm shytty with anatomy and had to go back and fix a lot of stuff. Once I got the anatomy down, everything else sped up quick as hell.

That's why I've always been of the position that the art pipeline should be mainly autonomous short of agreed upon themes and other predetermined special request.
