Cleric: not too much to do to this one.
Cultist: pretty much a complete overhaul (totally different colors).
Knight: not too much to do to this one, either.
Orc: a fair amount of re-working on this one.
Tannuruk: Seem to recall another decent amount of repainting for this one, as well.
All in all, I had fun re-painting these guys. The line of D&D figs really have a lot of good sculpts, and I have a fair amount that I'd like to re-paint (someday).
