I also produced character concept sketches for the Eagle and the Dragon, which I then took into Photoshop to test some paper textures and colours...
The Eagle on the left I made darker and had fiery golds shining through (as the Eagle is "corrupted by Morgoth" and goes through flame and sorcery to become a dragon):
Light parchment colours, was experimenting with how to make them look similar, as the Dragon morphs from the Eagle:
Experimented with adding flecks of foil gold to the paper texture as this is Smaug The Golden:
Tried a slightly cooler hue as I wondered if the paper Dragon might blend into the parchment-like map background too much in the film, depending on the final look of the background environment:
Turned up the contrast to experiment with the foil gold texture, kind of looks like fire on the surface of the dragon now:
Origami/Paper Trees Moodboard:
I also tried out a tree with the fingers/branches more closed inwards and claw-like (middle bottom).
Added a few leaves to the tree (middle top) which could be shaken or dropped off when the tree becomes more alive - as if the hand was in disguise.
Also drew a more simplified and origami design for a tree (right) which could be the surrounding trees.
