Wow... The perfect pinky website. I luv pink... You have placed the adsense ads perfectly. I think you can place the ad in the navigation bar just inbetween Menu and Cool links to get more clicks from that area. Try to use square ads in the body also...
I think the aesthetic qualities of your design may work against your CTR! What would happen, I wonder, if you made your links regular blue? For me (at least) pink doesn't say 'link' to me - and I think visitors would generally be better conditioned to respond to blue, underlined links. Why not test it at first with your horizontal block, where the links are dark grey already.
first of all, remove the horizontal scroll. Put more content/image on the homepage to make it attractive.
your adsense blending is very nice but i suggest you look your site with firefox. it does not look good with firefox
