My first attempt at a (at least semi) realistic character portrait, Ramona Flowers (as played by Mary Elizabeth Winstead) from Scott Pilgrim Vs. the World. I love that movie (and moreso graphic novel) so this was a no-brainer for me to try!
So the hair proved to be a learning experience; ZBrush's Fibermesh is pretty fun and easy to use, but wasn't giving me great results; Modo's standard hair/fur material was an absolute nightmare to try and figure out, but got closer to what I was trying to produce.
