Ear modelling

I have modelled the gorilla's ear as, which I also did with the aid of a tutorial.  I used this tutorial on how to model a human ear: http://www.youtube.com/watch?v=QcYrUHRIqsE.  I also used a photo of a gorilla's ear that I found on the internet as reference.

A gorilla's ear is a slightly different shape to a human's ear in that the ear lobe is closer to the helix (the rim around the top of the ear), but the principle of making it from a hollow Polygon Cylinder and then extruding the inner parts was the same.

When I fully modelled the ear, I attached it to Cornelius' head, by the vertices.
