I love the Anniversary theme, I think it's great, there are two things that bug me though, firstly, in the top left corner of the page, that pale red lion cub for navigating home... the colour clash is just... yuck, at least in my opinion I realise the same colour is used for pawprints of unread threads, but for me that's ok because it doesn't look so bad on the lighter colour. I'm almost inclined to want all the pawprints a different colour though (maybe greens?), rather than just pinched colours from the old default theme. Having said that, I do like the button and link text in red. That's my personal take anyway :P

Also, the reply button seems odd that you can't see the design until you hover over it, but that's not as big of a problem as that colour clash is to me.
