I did this for a small personal project and would like to share it.
I modelled and rigged the dragon myself, and also created the textures for the scales on the body.
This is my first upload to Blendwap, and also my first "complex" rig.
The rig works, although I'm sure it can be greatly improved. Any comments are welcome.

Layers:
1. Dragon mesh
2. Rig
3. Ground plane
6. Scales on the back of the dragon (not used)
7. Custom shapes for the rig

I hope people find this useful.
Have fun!
