Ad placement looks ok to me, much better than most. I do think your main headline is too large for the balance of the rest of the page and below the Surf! box it's a little too crowded.
Regardless of my ad placement review you should know proxy sites perfrom poorly with google adsense Consider this is a standard template I constantly see for proxy websites, I can only give it a grade of a C+. You see, being unique and different is what makes you stand out from other sites, it will take you probably one year at least to earn $100.00 USD. I personally suggest you find a better niche, something to earn you money that is worth your time and effort. Good Luck!
Try and keep them orderly not throw them around the page. People don't want have to look through all the adds to find your updates and captions.
