That looks utterly disgusting... which it should. Because its Nurgle. I like how youve painted the rusted armour on the legs and the sword, and it all looks very gooey :happy:. Not too sure about the base though.. looks a bit... clean? Might want to try drybrushing the grass a brownish colour to make it look diseased or dead, just to fit in with the rest of the mini, and maybe splatter some blood or pus around the place for that real Nurgle feel :party2:.
Have some rep
