Quickly: I never liked the old template: it had nothing to do with my style or personality. I hated the light text on dark background. This new look is going to take while to fix, so don't dig around, it's a mess! Whole posts will be white on white, or look "naff" - but it had to happen. There are still problems, like the way this text is too close to the nav on the right. I can't figure out how to pad that, but it'll get fixed. Anyhoo, I think of autumn like a new year, so this change rings it in!
I'll explain the banner later. xo
