Damaged Concrete

Hi, this is my first procedural texturing assets in Mari, I must say this is one of the most damaged concrete piller I've seen!. My process of creating the following textures was a combination of photo reference and painting in detail to keep the look unique to our Mari project.
I wanted to delve into Zbrush some more so thought it would be a good exercise to create some environment concrete pieces, I may potentially use these in future projects/environments.
