@Chaoszerox - I see nothing wrong with the new sun rays. They don't dazzle me though. But then again, I think that's one of those textures where there's not a whole lot that you can do. If you can, try to experiment one more time before calling it final. Something that looks like realistic rays of sun, that fade into transparency at the ends. Pull up the alpha channel for it and at the ends, fade it from grey to black instead of just going from white to black. Just my opinion, it may not look good but I think it's a quick and easy little experiment.
@Blooped Out - In theory your idea about roughing up the paintings sounds good. However, in game they're almost kind of magical. They're paintings, but they're not used as such. So I actually don't like the idea of roughing them up or making them look overgrown with lichen, moss, etc. They should really stand out.
Plus, I don't want to muck up your awesome art work!
I vote to leave them pristine and clean.
