Head studies (Patreon)

Some angles of the head really elude me. Gonna try and fill this sheet as much as I can. Done in Procreate.

For reference, I used Sketchfab. If you havent heard of it, its a site much like Deviantart or Pixiv but everything is 3D models. Some of the 3D models on there can work as good study materials, I believe.
