Large Metal Shed

I'm resuming the project because I had put it aside so I'm taking it back and I'm going to rework the 3d because it's too big in height
so I'm going to resize it and I'm going to master the PBR textures.
PS: It's the same photo because I didn't think to take another one.

Hello, happy new year already

Then I come to you because I finished the 3d part and the texture part.

What I need to do is put the PBR textures, that's what they are
the material describes the visual properties of a surface in a physically plausible way to enable realistic results in all lighting conditions.
