I decided to update my ZBrush Comic style material and in the process of refining it, I came up with this surreal sic-fi concept. Everything except the 'ground' of the final image is done in ZBrush, I just added a few texture overlays in Photoshop. The new material works quite well with Polypaint so basically 'what you see is what you get' from the ZBrush canvas.
I had a chat with the talented J. Hill about this project so if you want to see a bit of the process, here is the link:
I have also shared the material on my Discord server, so you can join and grab it from the resources channel: https://discord.gg/A35DmkWCPE
