This is absolutely AMAZING!! You've given this rendering so much depth, it almost feels as though I can just walk through the scene.
The sky is lit up in such a way that it almost looks ablaze. I also like the "haziness" you've included in the distant background. Also, I like the way you've used the lighting to pick out the forms of certain objects in the picture.
The landscape in the immediate background look almost "solid"
If it'd been me who drew this, I probably would have made the roc formations look a little more craggy and jagged. It all still looks pretty impressive, all the same.
I'm surprised that there's no comment on this picture because it is beautifully done, I'm impressed very well done my friend....I love all of the details and the colors. I mean that the sky gives a heavy atmosphere very hard to survive in.
