This picture is so nice i actually made effort to comment. That is first. I made my dA account to search for inspiration for my work as a magician and what i see here is perfect example of that. i will use it (hopefully that is ok with you) as my computer's wallpaper for a while, draining from it.
Wow...actually reminds me a bit of what the concept art might look like for a place in World of Warcraft...which technically is on another planet I believe! It brought back those memories, except yours is even more beautiful.
