I'm currently working on a small diorama set inside a concrete utility tunnel. I will be using Modo, Substance, and Toolbag for this and hope to push my Modo skills and reinforce my understanding of normal map baking.
I am not working from any reference, but I did start with this blockout.

Adding some lights.
I have a feeling some of the pipes will change, and I need to fill in the cavity below the walkway.
Next I want to create some low poly cables that can be used to replace these ones using curves.
