judging by site looks if it's first, it's far better than people usually put on here ... Add placement is bad in my opinion - not clickable if that's your goal. Work on site promotion, and unique content.
Good job, now keep improving it. I would consider what you have now a "rough draft." I say nice job, but that could still use improvement.
Solid job on your first site. And I think your ad placement is perfect. Now as the poster above said, keep improving it.
The placement is actually ok but the thing is that the ads appearance doesn't look blend in with the content. Try to change the ad unit background and color so that it matches with your theme.
