Hi everyone, I’m working on a 24×24 tileset and I’m looking for some feedback before I finalize everything.
The tileset is still a WIP — I don’t have every tile made yet — but I wanted to show the current state and get critique on the direction so far.

What I’m looking for feedback on
1) Overall readability and consistency
Do the tiles look clear and consistent as a set?
Are there any areas where the materials feel confusing or hard to read?
I’m aware that the grass+stone tiles need adjustments because the stone is hard to see, and the stone tiles themselves were recently updated (I included a small proto→current comparison at the end).

2) How should a tileset of this size be organized, especially with so many different tile types?
Right now I have the basic terrain tiles arranged in a grid (four rows of 96×96 blocks for each material), along with the vertical/horizontal doubles, U‑caps, and the solid 4‑way tile. But I’m unsure how to arrange the more specialized tiles — things like erosion end tiles, slopes, waves, loops, and the solo interior corner tiles. Should these be grouped by function, by material, or separated into multiple sheets? Any advice on how to structure a large tileset so it’s readable and easy to use would be really helpful.

3) Whether the fitment demo communicates the tile logic clearly
I included a small test map showing how the tiles connect (slopes, loops, waves, erosion, etc.).
Does this demo make the tile behavior clear, or should I add/change anything to make the flow easier to understand?

About the tileset
The set includes:

straight tiles (floors, walls, ceilings)

interior and exterior corners

slopes (gradual / normal / steep)

erosion transitions between grass, stone, and dirt

U‑cap tiles and double‑sided tiles

loop tiles, round tiles, and sine‑wave tiles

erosion end tiles, which serve two purposes:

placed together, they form a 24×48 floating platform

placed at the edge of terrain, they act as eroded cliff/pit endings

updated stone tiles (shown in the last image)

The PNGs below show the tiles grouped by material and slope type, plus the fitment demo.

Thanks in advance for any critique or advice — especially on tile readability and how to arrange a tileset of this size. I really appreciate any guidance.
