During winter break I did this short animation and a few other expressions to fully capture the character of Geralt and try how far can go the metahuman rig with my custom Geralt mesh.

More details and renders about the likeness of Henry Cavill as Geralt in this post https://www.artstation.com/artwork/Dv1LQO
