Hi! I'm trying to reach five stars on my island in order to start terraforming, could anyone help?

You can have up to 15 dropped items on your island before your rating drops. Check in with Isabelle. She'll tell you what you need to do: more fencing (girl loves a fence), clutter (dropped items), etc.

Thanks again!! I'm gonna look around and make sure there's nothing just sitting about! I oughta make some more fences and whatnot as well!

And save up your nook miles too, every action for transforming your island is purchased with nook miles. Water and cliffs are 6k the different terrain sand, dirt, pavement, etc are 2k each so it adds up

Wanna say in total for everything its 24k nook miles

Don't have too many trees though. My rating dropped when I had too many trees.
