i would go with a silver for the plates, maybe a rustic bronze you just need to have something in the model to pop out, or else your going to have alot of blue and purple that just looks like it almost smears together, and as for the wings, look at some dragons wings. somtimes you'll find that the underside of the wings are much lighter then the outerside, dunno to me the wings really should stand out on this model, and unless its like a lighter color, seems like it really would just be too much blue or blue/purple shade
