Here's the general idea from a tiny sketch.

Very rough, and it's just the general idea to get all the flaps in place. I'm gonna test fold it now and see how it turns out. I'll base it on a big grid... Mabey 64x64 or 72x72, because i need as many pleats as possible to spread on the wings, and more flaps to get the toes on all four wings. The head will be full of flaps too, because i'd want to have feathers on it aswell. If the paper can handle it, i might go for a 100x100 grid, but i stongly doubt it.
