Thanks for the kind words so far.
The rider and the mount are two seperate colours, I clearly need to work on the exposure settings for this camera.
The carnosaur's skin was achieved by blending Shadow Grey up through Space Wolves Grey and Skull White, whereas the old blood was done from Enchanted Blue up through Ice Blue to Skull White.
I do agree that I could have done more with the scales. The red isn't as vibrant as I would have liked. Perhaps more orange would have helped.
Thanks again for the comments =]
