If the party crosses a frozen forest next session, this pack draws it: snow over spruce, needle duff under the trees, reindeer lichen, a bog, a frozen river with open leads in the ice and a log cabin with a woodpile.

It ships a finished 36 by 24 map called The Frozen River, as a PNG and as a Tiled file you can redraw for your own crossing. 345 tiles at 16x16, and 282 of them are transitions, so the snow, the bog and the river meet properly. Thirteen objects each carry a contact shadow.
Every tile comes from a procedural pixel art engine, not a diffusion model. The pack and its art are AI generated. It's $6.99 while it sits in the Verdant Complete III sale, $9.99 after.
