Wow... This is really good! I like the way you did his posture and expression. It makes him look like a very comfortable flyer. The sunrise(set?) colors, and his wing colors are very striking. Very good.
That's the feeling I desire most from our world. To soar through the air, with the wind rushing past my body and soul. To see the sun rise over the landscape, reviling all the wondrous life below. Fly and fly, t'ill my wings are numb. Then fly closer and closer to the ground, just a touch away while gaining great speeds. Then in the blink of an eye... A cliff appears from nowhere and I shoot right off it. Now the true beauty of the world has been reviled. A valley of the most beautiful flowers just below, untouched, healthy and colourful.
Now why oh why can't we have wings... I will never know. Awesmazing work, it's truly inspirational. To think I was just about to go and look something like this up when I happened to notice it in my notifications.
