hi guys, as a practice, i made this shield model using some geometry nodes magic and a bunch of modifiers. the issue is i can't figure out a good way to make materials for it.

there are essentially 5 different materials i want to make:

1. the main wood obviously (the one on the screenshots is just a placeholder)
2. the outline metal (i managed to make something which looks half-decent, but would like a bit more roughness and details)
3. the central metal (i want to give it a bit more of a rough bronze look)
4. the wooden handle (more weathered look)
5. leather inside the hemispherical inlet.

i was wondering if you have any ideas on what resources i could use. or any specific techniques to make it look more realistic. i like making procedural materials, so anything along those lines would be a big kudo!

also of course, any comments on the overall set (lights/environment map/rendering settings) are also more than welcome!

PS. also, of course, would be happy to share the blend file if you're curious (although i don't think it's too complex of a model)
