Indeed, the layout, color scheme, the head/banner, nav bar, everything looks great. The flash ads are complete overload and would drive me away within 2 seconds if i'd come in as a regular user and that's not even considering people that are photosensitive.
You've managed, as one of the very few, to get the ad placement exactly right. Not wasting your prime real estate for ads that are hardly being clicked, yet you're retaining intelligent placement options for your ads in the other spots. Solve the flashing problem and you've got a total winner for your type of site!
Also, the recurrent theme on your site is the distinctly shaded "green" color that you're using in the nav bar buttons, use an identically shaded button as your favicon.
