Ahriman
Ahriman, who has been sat in pieces, half-painted in a box since the model came out several years back. A bit of spring cleaning... it's so rewarding to pick up something that was left unfinished and unloved and just getting it finally glued together and (mostly) painted.
Fun note, he's magnetised so can stand on a regular base instead of the disc of Tzeentch, but who doesn't want a daemonic means of airborne transport?
