ROM Hack NHSE terrain edit question

[Deastrumquodvicis]

Pretty new to the program, but I want to turn a quarter of my island into a mini-island. Problem is, whenever I use the acre editor, I end up with either ugly sharp lines or a significant loss in land area. Is there any way to turn individual squares into a beach without using the acre changer?

I dont use terrain editor a lot, but i dont think there would be a easy way, only by manually terraforming, i tried once, but im not the best at that

I used the acre-edit thing, but now my internal beaches look like this. I have no idea what’s causing it, but it’s making my game lag.
