I like the colours in the dirt. The lower contrast and cooler hues make them feel lit by the same blue sky as the grass.
However, aside from the colours, your tiles are identical to my edit :/ Please do your own work! Apply what you've learned from my edit and draw your own dirt according to your tastes. You'll learn more that way and be able to do better work on your next bunch of tiles. Plus, you copied my mistakes/laziness as well! The edits I made for you don't tile well with your existing grass-dirt transition tiles at all, they make noisy-looking shapes instead. You should probably also have more than just one tile for the middle row of dirt-tiles, as it gets rather repetitive even with the more organic shapes.

A WIP of the new tile set... I'm really having a bad time with this, what should I do when i'm blocked like this?
Anyway, some tiles have not been edited yet, I want to check if this style for the rocks works, is this better or worse than the last one?
Sorry for using your edit, I liked it so much and I really think it was way better than my edit (even if is a lazy one, you're a pro after all XD)
Thanks
