Nothing special

I think you did a nice job.
Suggestion:
The fonts are perhaps a little small, try bumping them up some– but do so on an HTML document first (embedd the CSS), so that you can use your blog while you experiment. Fooling with font sizes can easily turn it into alphabet soup.
Try setting 100.01% on the body. Then % or em’s on the font sizes. Em’s are a little easier to work with. Either way, it’s trickey– just go slow and be patient, you’ll catch on to what controls what.
