Skin3D but not cubic

One day I woke up thinking that standard skins look rather boring due to flat layers. After trying various 3D skin mods, I noticed they look unnatural - additional cubes turn out larger than head blocks and create a strange effect.

Eventually I discovered an interesting visual approach. Yes, the result might seem unusual, but why not share the discovery? :3

The mod allows configuring various parameters through a configuration file, and all changes are applied instantly with a simple texture reload!
