Final, changed the rivets to be brass instead of copper, swapped the uniform colours used for gradients based on the noises used for the material, and colours from the reference (except for the corrosion).
Third iteration, replaced the rivets, and added some hammering damage to them.
Second iteration. Updated heightmaps and noises to be less crumpled, and closer to the reference.
