The GDC clip is basically him talking on others people work completely unrelated to what he's supposed to sell. High five!
EISKO released their 2017 head data package, a product for both VFX/offline and real-time environments. The pack features a full female head model (both low and high poly versions) and some high-quality physically-based 4K textures for face and head props from the studio’s capture system. The best thing is that it’s all free. Go on their website or download a version here, download a version of the datapack and start building up your render scene, be it in Arnold, V-Ray, Unreal, Unity, etc.
A closer look at the project:
On the left, a ref photo under flash+daylight conditions, and on the right, a render with no comp but a slim hair mask and background. This was done in Arnold and Maya with a home made skin shader, and using the VFX data.
