I finally managed to get a bit of brush time in a few days ago, and the results are the finish of a few terrain bits. While technically all of this is 25/28mm sized, they would work well for 15mm too.
These are from the Battle for Macragge Starter set.
I use them as a sonic barrier for Venus or any other Sci-Fi setting.
I would buy more if you have any...
The Sonic Disruption Fence's power supply.
A mysterious obelisk on a brick plinth. Innocent park decoration?
Or cleverly disguised arcane focus for Elder Gods?
Naturally, I now realize I probably should have taken a few photos with, oh, I don't know, maybe a figure or two in the frame for a size reference! D'oh!
