Love the tilesets and the diversity of biomes so far...
As I would need a cursed/dead forest tileset (dead trees, torn shapes, weird inscriptions on rocks maybe, baren land, dark dying grass, dirt, a few animals skeletons...), but can't commission it (can't imagine the price for 2 months of work), i was wondering if this might already be on your to do list or even a good idea for a tileset.
Other than that, keep up the awesome work, i'm progressively buying everything you made, its dope.
