This is my first try in ear modeling. I used a reference drawing (made by myself) to clarify the shape of curves and folds. Started with a zsphere and modeled using edge loops.
Attachment file shows the wireframe model in low subdivision level. You can see three edge loop levels, that form the ear.

I have tried zbrush for about a month, this is actually my third model in zbrush that I have been working on
