Only two errors in the CSS but they are related to some music thing you got going on.
I think it's marvy, Geeks, though I did have to pump up the text size a notch. I hate tiny text.
I do have a minor design suggestion. The boxes around the blockquotes are fine, simple and ....okay, boring. Instead, how about a few of the bubbles from the background acting like "quotes" around the blockquotes and throw away the lines. Or the kiss lips as a watermark effect to the upper left corner of the blockquote or the lower right corner - going with the "sealed with a kiss" kind of theme in the blockquote. It would just add that little touch of fun to the post area that seems to be....well....needed. IMHO.
Very great and very vivid. Love the look. Like the use of "bubbles" for the bullets, which is what made me think of tying in the bubbles or the kiss to the blockquotes. Or bubbles on the blockquotes and a small kiss for each title....have some fun with it.
Later I took another look, all the way through, and noticed that on the post_nav_links() you have both a plus and a double arrow. Pick one - I vote for the arrow and the plus it hard to see. It looks sloppy on a slicko site.
