I had this idea one day to make a bodyguard-themed iron golem texture, and immediately thought of Brock Samson. I wasn't happy with how my 16x version turned out, so I went with 32x instead. This is the one I run in my personal resource pack.

Bloody damage textures:

I hope this inspires someone to make a higher quality one.
