In December 2017 my new Blender video course will be released: "Mastering Sculpting - The Ultimate Guide to Dynamic Topology Sculpting in Blender"
It will be a (paid) video training, suitable for both, beginners and advanced users.
P.S. A big THANK YOU to RenderStreet, which helped me to render this teaser: https://render.st/
