A 12 part commentated video tutorial series that covers the digital painting of facial skin tones, with various techniques and tips. This is the completed face sheet. It's not very good from a compositional standpoint because of the faces was approached as a unique object. I hope people find this all helpful.
Cheers. You can give crits or ask questions either here or on the videos. I'll do my best to answer and questions and improve my methods in future videos.
