I'd be interested to see it with a different background colour - personally I don't like black and I think a lighter colour might make it look much nicer.
Not too keen on the ink blobs on the right as they make the text on top harder to read.
I'd put some right padding/margin on the calendar - looks too squashed to the right (although I'm never sure what the point of a calender in a blog is anyway).
Hope this doesn't sound too negative as these are only small points. And what the hell do I know anyway
