This is the first Nurgle character i've attempted, and i experimented with using lots of wetbrushing and glazes/washes on him to speed up the painting time, in total i spent around 4 hours painting it which i don't think is bad considering how he turned out.
The colours i used for the armour were a mix of black, scorched brown, dark angels green and catachan green, and this was brought up by adding bleached bone, and then washed using the original mix watered down. the rust is simply bestial brown watered down and feathered, and the armour was tinted using various colours, mainly glazes of dark flesh in particular areas.
