The hair… wow, that looks so good and seamless. As if there was any doubt with your work!
However, I do have to nitpick as well. There is something a little bit off about the brown cloak. On the left side, it’s almost… slanted too much? It almost looks like it’s floating on him. Maybe there needs to be some more shadow on the white robe to blend it in better? Something like that.
(Not trying to start a hate swarm, it looks really good regardless.)
