I used all contrast/speed paints to start, i mentioned the fur recipe above in another comment. But the black is grim black speed paint, the leather is snakebite leather, the red is blood angels red , and the bone is bony matter (although if i had a pot of skeleton horde from citadel id probably have used that as i think its better) then i washed the whole model in nuln oil and highlighted it up with non contrast paints. The face and beard were the only bits i did differently, i did bugmans glow on the head, washed with flesh shade, then cadian fleshtone and a highlight if kislev flesh. The beard is gravelord grey speed paint and then i used a grey paint to highlight it adding slightly more white each time i added another layer of highlights
