I based one of the creatures in my film on the Assyrian/Babylonian demon Pazuzu. If this figure looks familiar, it's probably because he's the antagonist in the Exorcist movies. Max Von Sydow's father Merrin confronts a statue of the demon in the beginning of the first Exorcist movie. There is at least one very vivid real-life statue of Pazuzu, and I based my design of the stop-motion puppet on this particular one.
I added some color to the feathers with my airbrush. More paint was added later.
As usual with my puppets, this fellow had a foam-padded body, covered with patches of cast latex skin.
The support wire of the finished puppet was simply attached to a large block of wood, and held still while animating with a clamp.
The top part of each wing was covered with fake fur, glued on with contact cement.
The ups of making your own feathers using sticky tape is, of course, that you can decide the size and shape of them, and that you don't have to use parts from a real animal, if that makes you uncomfortable. Fur and feathers are not always removed humanely, and that is an issue for me. Another advantage is that you can actually animate every feather, and bend it as the wings flap up and down to achieve an admittedly more cartoonish, but also very dynamic movement. I'll be experimenting more with fake feathers eventually, and try to make them more and more realistic.
