Has the rough look of a squatting site. The bold, underlined titles remind me of the style used in v|agra spam. The google ads are too numerous. I strongly recommend getting rid of them until you get serious traffic. They'll turn away potential users. Okay--those are just style issues, subject to opinion.
And about the ads: You don't need them, especially at this point. You don't have the traffic, I assume, to realize any type of real results from those ads -- and in the meantime you might be scaring away potential users.
