Making Money Blogging

Cast your experienced eyes over this site guys. All the sites I have look very similar in appearance to this one, so any ideas or such can easily be applied to the rest of them. I'm looking for feedback on ad placement primarily, but if you can come up with anything else than that would great.

I've ran the site through - Blog Stew so I know of the 5 missing alt tags, still 91% aint to bad!
