[substance designer] I made some reinforced concrete, I need some advice.

oraeles77

these textures have height maps etc, which dont show in Substance designer, but I was wondering about some advice,  regarding the top texture and the way the metal rods penetrate the concrete, as the concrete looks completely flat and if a stick was to penetrate a gel surface you'd expect distortion in the shape of the surface etc? what do you think?

also as the metal is rusty, I

this is the metalic map, as its rusty, I decided to keep the rods very un metalic. any suggestions?

and here is a brief sample of the other maps, I think the normal could be too dramatic which ruins it, I kept the roughness very white to make sure it wasnt shiny.

I used the dripping rust nodes as well as the mask builder node.

any advice is welcome.
