Looks nice. Like the layout and the colors.
Only thing that I can think of that I would change would be to shade the "Filed Under" section so that it is distinct from the rest of the post.
Also,if you have a lot of pages and/or a long blog title, it messes up the formatting of the top bar.
I have your theme active on my site currently, as I'm checking it out, and you can see what I mean.
It may be a resolution issue on my computer, but I'm not sure.
Overall, I really like the theme and may continue to use it on my site and just customize the layout of the sidebar and some minor formatting stuff to suit what I need.
