I started with a clay mask that I sculpted directly on my face because I had nothing else to lay it on to keep its shape. I packed tin foil onto my face and began laying on slabs of clay. After I had the right form, I found that it would stand up if placed over two upside-down kitchen bowls--one big (forehead), one small (chin). From there, I finished the details: semi-circle cuts for a feathered look, nostrils, shaping the eyes, etc.
-Here's the mask in the oven:
Then, as with anything else I make with super sculpey, I painted it with acrylics and sprayed it with a finish/fixant. The colors are based off of the peregrine falcon, with a few creative liberties to accommodate for a human contour.

The rest of the costume was essentially a black leotard with a white Egyptian-style loincloth and an ochre cloth head-dress. Unfortunately, only one picture of me fully dressed exists, and I don't currently have it. As soon as I get it I'll update this post.
Now to start brainstorming for this years costume!
