I think it looks ok, but would personally prefer black text on white (or similar colour to your background picture/background of the banner) background.
I think it looks good. :) Not too much white at all. But same with Ladyschrei, I'm on Google Chrome so idk how it looks on other browsers. I like the blog layout too. ^.^
I think everything looks fine, not too white or anything. Very easy to read. I'm on Google Chrome though, so it might look different to someone else on Firefox or Internet Explorer.
