I'm the same way. I really don't have an eye for design so I've always stuck with super natural-looking towns because I can't even begin to count the amount of times I've tried to copy the kawaii and zen towns that it seems like literally everyone did with New Leaf, only for it to turn out a mess. I find it hard not to feel like you're doing it "wrong" when you see the kinds of things that other people are capable of but the point of the game is that you can do whatever you want at your own pace so I try to remind myself of that when I feel that way.
