It's taken a while, but I've now got all of the base stonework done for my Tomb World terrain. 🫠(The pieces off to the left are the fully-finished test ones I had done previously.)
The stone was definitely the largest job, theoretically it should be faster going now because there's much less left to paint in terms of surface area... various dark green bits like the archways built into some of the walls and a few other pieces, some glow effects, then it's just highlighting those various colours (including the base white of the Necron walls) to make them pop.
