I feel like sometimes people take designing way too seriously with their islands which is one of the reasons I've seen people get so mad and frustrated with the game. I mostly blame Social Media for trying to compare who has the better island. The reality is there is no such thing as a "perfect island" your island can be just as good as long as "you" are happy with it. You don't need to let people tell you otherwise. I know from experience what it feels like to feel "pressured" to have a great looking island, but at the end of the day, just make what stands out to you.
