Learning to model organic forms such as the human face and ear presents a unique challenge for one attempting CG organic modeling. But as Blender has evolved so have Blender related tutorials. In these two organic modeling tutorials by Jonathan Williamson aka Mr_Bomb, he takes you through his detailed approach of the face and ear.
Jonathan who is self-taught, used a few tutorials in the beginning to teach himself and asked questions around on the forums. But for the most part he just kept experimenting with Blender and studying other people's projects, seeing how they did it and then trying things out for myself.
Jonathan's been using Blender for about four years and his passion lies in creating characters, most of human form although he certainly delves into other forms from time to time.His current long term goal is to produce a DVD modeling tutorial series.
In his face tutorial he takes you through topology and edgloops complete with background pictures. You'll find this tutorial at Blender Artist Community Journal #2 at the bottom along with some background reference pictures to download.
The ear tutorial can be found at Blender Artist
