My personal recommendation is to just practice + consulting with other mappers - I wouldn’t trust to a random generator, particularly when it comes to a map.
It honestly doesn’t look that bad - It’s a portion of a map that looks like a town square. City maps are low on variety because cities simply look a certain way and the tileset itself is fairly limiting.
If i didnt have usenti it would have taken forever to finish.
It wasn’t that much drawing it was mostly changing how the colors were distributed.
Also, I made it so that it works with Lyn’s palette
Also,
you removed a lot of detail by getting rid of the other shades(and the shades that are left need more contrast). Try some thing more like this.
(Honestly this is probably still a bit too saturated…)
This should be right at the color limit, but I had to get rid of a shade on the claws.
