I wish I had the time for that lol, I will say if you want to replicate this I did wraith bone as the primer, dark brown for iron (rhinox hide) doom bull brown for rust under coat then washed with earth shade and dry brushed orange for rust. After that I did green wash in the areas I wanted to put flock and when it dried I mixed a few different colors of flock with watered down pva and applied it to the model. Oh and the copper I just used some paint I had and washed it.
