You need a privacy policy per goog's adsense tos. Coz even though you don't store any pvt info about the surfer, goog sure does.
Also, your file size includes the size of the images on the page, so more like 30k and not 3k.
You might want to consider adding some more on topic content, this looks just like what goog classifies as mfa (made for adsense) and liable to put your entire adsense account in jeapordy.
