Thanks for the amazing tilesets! They look great.
* "terrain variationsT.png" has a handful of pixels with #e13c8a which should be transparent. They can be found in the bottom row of every hill.
* The ground of the first preview image is misleading. This base tileset comes without ground patterns applied. While some ground patterns are included as separate tiles, the base tiles are all have single colours. The ground pattern with grass is not included.
* The second (ocean) and third (camp) preview image tileset. Only the houses and the well are included in the tilesets.
* Typo in the file name: Terreins -> Terrains
