Greg, on former occasions I wonderd how much effort it has cost you to make such a wonderful creation. Seeing this post with all those perfect details, think I know the answer now.
Thanks for sharing. Just great, my friend!

I can't decide if that is snow or ash from a volcano somewhere EDV. Whatever it is, it really works well with the rest of the scene. The multi colored sky is great as well. You do nice work with your dragons.
Too often computer-generated images end up looking too contrived and artificial. Yours has the composition and feel of a fine Edward Weston landscape photo, although the purple color and the dragons tells us we're not here on Earth. It might be an interesting exercise to render yours in black and white to focus on the form and texture of the mountains without the distraction of color.
Check out the site "Between Truths", read, learn and pass on. The three steps is all you need to remember to get started. =)
