I already have the DA available in my signature, but I've got myself a little island I like to call Wahu - the island I've had since a day after the game's release. I've put quite a bit of effort into it, and I'm always looking for inspiration on how to make it better. Island pictures are available
here.

I'm also currently working on another island on my old switch: Parkwood. This island is purely for looks and time travelling, while Wahu is mainly my completionist island as I'm very close to completing all the Nook Mile achievements. Both are themed about the same: residential town area with a county part up north. I also like to imagine Parkwood as an island that is essentially Wahu, but with all my already-known knowledge of the game's decorating abilities being applied from the start. Overhauling Wahu would be super time consuming without time travelling, hence why Parkwood was created. I'll post a dream address for that island in another thread and try to gather some feedback there.
