Hey It needs more normals to determine what it is... is a little bit flat Also color variation and some info on the roughness to help defining the materials. Use more referencing for it! Hope it helps
It looks better, but to me does not look like it is Wet. Looks more like a lacquer. Post your texture flats, Albedo, Roughness, Normal Map, Metalness etc. so we can determine what the core issue may be.
Your roughness doesn't really look right, it should, if anything, be more binary imho. That is, either it's rough or its shiny (if there are puddles) and if there are puddles the normal map should be flat in the area where roughness is pure white. Otherwise, concrete will usually absorb water and go dark but not be. Like…
