This was a very intersting miniature to paint up, not something I would have bought myself just by looking at the bare metal.
It was a commission piece for somebody's bloodbowl medic for a necromantic team. I enjoyed painting up the rust which was a mix of drybrushing and washes.
Drybrushed PP Battlefield Brown - GW Snakebit Leather - GW foundation Orange - GW Silver. Then when dry a black wash and an orange wash. Highlighted bits silver again and a pin wash of black where needed. It gives a nice rust colour and the rough drybrshing gives it the texture of rust too.
