This is a quick video where I'm just working on adding some materials to a quick base model I made. The workflow is entirely procedural and no image textures are used, just Blender's internal noise textures to attain visual results.
I wanted things to look similar to the original reference image but not exactly the same.

Let me know if I did anything wrong! There's always room for improvement!
