Sburb64 level ideas?

Hey it's me that guy who made those HS Mario 64 levels, you've totally heard of me I can tell by your confusion.

I was just wondering if anyone had any ideas for new levels for me to make? The best ideas I have right now are all of Alterniabound and Openbound since those have maps, possibly Prospit and Derse? I definitely wanna continue making levels since Mario 64 is just fun to make stuff in and I'm curious to see what areas people want to explore.
