Those clouds have to be some kind of cheater paint that, when applied, dries in pixels.
Great job man!
Beautiful...but an odd composition with the character on the same side as the castle. The left half of the image serves no real purpose. When in doubt - use rule of thirds.
I agree with Kosvid - I love this. After having watched Lord of the Rings recently, it feels like a part of that same universe. This is a great little piece.
Excellent.
