This is my second attempt with Cinema 4D, this time I tried some hair lighting and coloring. I know the background is a mess and the lighting is not that good, but this was so much fun to work with, and there are so many applications you can extend this to!
I followed a greyscalegorilla tutorial for this, i think. 130000 hairs on a simple sphere, brushed a bit, just to give it a more stylish look. Rendered at 3543x3543px, 300dpi, in about 3 mins. Pretty quick. It's interesting how quickly, given the settings.
