Changed the model a bit, spent more time on creating the texture. Tried different ways and approaches to do it. I used a lighting map for the light, for better effect.
The basic principle is that the material is bronze, with trichines that have slightly lost the properties of the material. I splashed some blood on the texture. As a result, I achieved the desired look, so I think it's a good result.
