It's ok, but you really need to personalize it a bit--at least get a header made or something. It's so cookie-cutter the way it is. Also, the text is not so easy to read--if you can make the definition between the background color & the text color a bit stronger, I think it would really help your users. As far as the layout--nice job!
You should have some image or something at the top. Something graphic. Or use image ads only for adsense.
