I really like that Troll. He feels very Fairytaleish in a bone-cracking marrow-sucking kind of way, and yet realistic without the 3.x Dreadlock thing going on. 3ed trolls looked kind of stupid to me.
It was that drawing of DiTerlezzi that made me discover Planescape. I love DiTerlezzi's art, and my vision of tieflings (and other planar beings) is forever modelled by his drawings.
