Yes! Awesome tutorial, @Avery! Boring and unnatural natural terrain, especially cliffs and rivers, are something I see a lot of in RM screenshots, so I truly hope your advice helps newcomers and veterans alike.
I'd love to see a tutorial on how to make rivers look less weird and unnatural. I find it fairly difficult to make things look good when using the water autotiles for natural water sources; they're fine for manmade things such as canals and sewers, though.
Yeah, natural terrain and the blockyness of the tiles usually go not so well with each other^^
I thought about rivers, though my intuitive apporach would start with a huge amount of edits, so that is probably not everyone's go to^^' Maybe one day, that would need a lot of trying and erroring before I consider writing something down ;3
