/vt/ - Virtual Youtubers

Hello there! I am developing a small game about Watamelon, and I am working on a level based on Towa.
I don't know a lot about her, so I came in here to ask for help!
I modeled a Bibi Tower (pic related), but I need some suggestions about what song should I use as BGM,
and what can I prop it with, like a specific type of tree or flower. Any idea is welcomed!
