It's not my first head i have ever created, but its the first time i used sculpting for most of the head. i started with a base mesh of 244 faces and increased poly count with multiresolution step by step. Then i decided to built up a low poly repology mesh (2468 faces). i applied the normals of the sculpted head to the low poly one and also added a simple color texture (just a frontside shot of my head).
It was just a training for myself but maybe someone is interested in how i did this.
