So I spent a fair amount of time working on and off this in my spare time, but I finally got around to finishing it!
Sculpted and painted in ZBrush, imported into Substance Painter for other passes, texture adjustments in Photoshop and multiple edits to the Redshift material until I got the desired look.
Support and feedback would be appreciated! - Oscar
