Hi, I like the result you achieved on the armor with the turquoise wash. It's really nice but I don't know how much it fits the model. I think that it is too decadent for a miniature like that. It's an imperial knight with colored feathers on a really colorful horse, I think he takes care of his armor and avoid it deteriorating like that. I would see that effect more on some Undead or Chaos knight than on shiny imperial noblemen...
But that's my opinion, and the painting stays spectacular no matter what!! Great Job
