I found this artwork elsewhere and placed it in a folder of tons of dragon wallpapers. when it finally came up I was like "I MUST find this artist... Thank GOD for you putting your name on it in the bottom corner or I would of never find you!
Whoa, this really is an amazing place. I like how the canyon retreats back into the huge mountains beyond. And those clouds are developing pretty rapidly for this early in the morning. I bet the active clounds would make it a good flying day, and your dragon could probably make it to those distant mountains on glide, if he wished.
But why would he? I love how he's sprawled out across the rocks, like there is all the time in the world. I wonder what the sunrise looked like from his perspective.
I don't think I'm the right person to ask. If I were to analyse it I would say dragons would be more developed like birds and higher dinosaurs to be endothermic (warm blooded). But then again, it's fantasy so just decide for yourself.
