For the most part this deserves a decent grade. Your ads are in a place where it's not too distracting but at the same time flows nicely within the content of the pages. Blogger gives you a lot of options when it comes to adsense ad placement, so as long as you keep using this tool and test constantly you will eventually find your best converting combination of placements.
While the ad placement is okay, but am wondering what will motivate the visitor to click on the ads? The main thing is not really the placement, but the ads should appeal to the user and motivate them to click on them.
