Thank you! I actually have a Google doc setup with mostly links to various 15mm minis and sculpts that work well at 15mm, and am still testing out my 15mm measure stick to get it the way I want it.
As for terrain, the best part of 15mm Frostgrave is that terrain is super abundant because hobbyist stores carry a ton of it from Railroad and historical wargaming, and 3D printing 15mm terrain (FDM) is really cheap and scales super well from 28mm, unlike 28mm minis which can be hit or miss at 15mm.
Is that FDM or resin? If it’s FDM, that’s extremely impressive! They’re great regardless, a big fan of classic red skeletons, but on FDM that would be a mighty feat.
