I propose a healthy dose of washes and glazes on that dragon. It will help to give more depth to the red tones. If you really want a lot more depth: coat with satin or glossy varnish (sprayed on very lightly with an airbrush), apply glaze, drybrush, seal with varnish, glaze, drybrush. repeat until satisfied. (it's how i did my Blood Angels and I was surprised at the depth that technique gave)
