I would absolutely love to see more culture in Skyrim. The music in taverns idea is great, I'd like to hear different kinds of music depending on what region in Skyrim I'm in. And I'd like it if not all the taverns were so damn neat! I want the place to be cluttered and messy if a bunch of raging drunks reside there, especially if there's a raging drunk running the place!
I, too, have noticed how boring and repetitive the paintings were, they were cool and pretty until I'd seen them so many times that I could paint them myself.
EDIT: So is the moo option a yes or no?
