Instead of solid colors, try using gradient. This will surely add to the beauty of the site. Even the font (type, size and color) need improvement.
WAYYY TOO BUSY! There is so much going on on the website that its hard to differentiate between advertising and the actual website. Half the time when I thought I was going to click on something, it was like an ad rather than the site. I'd say you need to really add more whitespace and separate the ads. Just my opinion on it.
