I quite like the style of the ground tiles, the differently sized square stones look good.
I like the corner bumps aesthetically, but I think they're creating gaps between the rest of your assets, making the trees, spikes, etc. appear to float off of the ground.
The LDTK auto-tile is much appreciated! Although I think the .png file is missing some tiles (If I remember correctly, LDTK can generate some tiles through symmetry, though it would be nice to have those tiles in the .png if you plan to use a different level design method).

Thank you for commenting! The height difference bugged me too, but It didn't really want to change them after the fact, in an actual game engine you could probably work around it easily. Missing tiles are just a question of copying and symmetrising them yourself, just that LDTK does that automatically, and I wanted to have more than just ground tiles on the image.
