11. Edit this region, mobing the polygons:



12. To give some volume to the ear, extrude the external edges 2 times, as highlighted:



13. First test of subdivision. The ear should look like this:



14. Moving some vertices, edit the mesh until you have all the anatomical details, as you can see from the low-poly version:



15. ... and the smoothed version:



16. The back part of the ear should look like this:



17. ... and like this smoothed:



18. The ear viewed from the back, the ear should have a shape similar to this:



19. After moving some vertices and adding some details, this is final result in low-poly...



20. ... and smoothed:



21. Here you can see the render. All the anatomical names are mentioned (in portuguese):
