Super Sculpey: Creating the mechanical ear

I wanted to make VeePees' mechanical ear in clay so I could understand the geometry and shape of the object better. Working from this reference will now help me in further sketch work and 3D modelling.
The cone shape didn't come up as smooth as I would want it and the cone is also too thick, so I will learn from this and continue on.
