What is Awesome~!
Your detail on the dragon is fantastic, the scales and spikes are very well done. All the colors go together very well especially with the accent of the sunrise/sunset. The mountains are fantastic, I love what you did to show the snow and your landscape is very well done. You also did a great job on perspective~!
I didn't realize this till I lived in an apartment and you can actually see when you look on the horizon that the world has a slight curve to it. So that is a good thing to keep in mind for future artworks, when dealing with heights.
You have a very imaginative style~!
KEEP UP THE GOOD WORK!!
