Great Model, man. Father Nurgle is great. The only i could say, is that his cloak and the horse's skin are too similar. Maybe you went for a complementary look, but for me it just looks bland. All in all,
amazing model dude.
Games Workshop should review Nurgle and give them a mount. Slaanesh has those fiend things, Tzeentch has their disks, Khorne have their Juggys, and Nurgle has..... rotting horses.
Plague-beasts would be a good idea.
