I know nothing about modding, so all I can do is offer suggestions for some interesting mods, should other like to try them.
VV2 has my favorite outfits, and I'd love to see them in this game.
I love the new hairstyles. They are my favorites out of all of them, with 2 exceptions: The blue-haired and rainbow haired girls of VVFamilies.

A less "pink'n'purple" Love Shack. How about some green and blue? Or Neon green and orange? :P Maybe a palm tree instead of the hot tub?
Maybe different colored cloth/cloth pulp?
Just some thoughts. ^_^
EDIT: Oh! And what about dragonfiles instead of butterflies? That would be lovely!
