How do you plan your island?

I have just unlocked the island designer app and did some brainstorming for how I want my island to look. Top left is my original map.

What do you think? I want to keep it natural and have my museum and camp area as pretty big spaces with lots of trees and greenery. Idk what do do with the space between airport and resident services, maybe a little market area for the town center
