It has always been incredibly hard for me to gauge what makes a character interesting without it conflicting in some design aspect or aesthetic manner.
He was doing character design for them. He was incredibly good, and practiced every day, for hours, to the point that I was wondering how his hands were not falling off.
The hard thing, though, it seems, is that it's a bit like a musical composition: It can take years to master, but any peasant can hear when you play just a single key wrong.
