Base coats were done in zenithal layers of Tamiya black, purple, and red, then the entire mini was given an overall filter of Tamiya clear red. After that, I gave it an overall wash of Secret Weapon black red wash, then painted all the bronze gilding and misc. details in Vallejo.
I then applied several red/brown oil washes to the entire mini and added the verdigris effect with dry pigment mixed with an oil wash. Once that cured, I gave him some additional weathering using AK/Mig enamels. I also used this mini as an experiment in doing old caked gore around the chainaxe. This was done by applying thick layers of de-oiled dark brown and dark red oil paints for the older gore and then using a sparing amount of bright red and brown oils, directly from the tube, to simulate more fresh gore.
This was a fun mini to paint and a real departure from my usual work. I wanted him to look like he'd fought thousands of years of brutal campaigns for the Chaos Gods. If you want to paint your own, the model is available on Cults:
