Finally managed the finishing touches on all the NMM, and I've attached the big guy to his base. Still have the Cryx-y glow to add and some more details for the base, but its close!
The NMM gold is pretty simple:
-Citadel Desert Yellow
-A couple applications of Flesh Wash Glaze (Flesh Wash/Matte Medium mix)
-Reapply Desert Yellow
-Citadel Bleached Bone
-More Flesh Wash Glaze
