So I've got conflicting light sources, mainly in the close arm and his left (our left) thigh.
You're dead on about the close arm, Iv'e been going back and forth with that, tryiing to make it both fun to look at and technically correct. Still not finished with it, apparently. The shadow on the left (our left) thigh is being cast by his overhanging arm, not the manpanties. Though I suppose that would be clearer if I had rendered his that arm correctly in the first place.
I'll get right on it, boss.
