I see this and the only responses I have are excited exclamations that contain many expletives. So I will say simply "well done" to spare everyone from my geeky vulgarities about how awesome this is. FYI I came across this via io9.com so they are great overall and also great for linking to you.
The giant dragon that brings about the destruction of lands, such a work is astonishingly wonderfull. You have made it really well detailed and I had to place it as my wallpaper on PC. The mage standing in the middle give andditional beuaty and better feel of the world that you have shown us. World of mighty dragons and magic which flows in humans veins and lands. Even though it is not apocalypse it certainly looks like a one, if such majestic dragon would appear in our world it would certainly rule over by now with its minions.
