very good grapgic i hope you see my frist blog and give me your opinion cars-carss.blogspot.com ok i wait you
i think the main content window, the white part, is a bit too dull, maybe try some graphics on the outside, or something with round corners or gradient per haps
The Ads background of yellow is too striking..you might want to blend the color with the template. Again find a suitable template with the wider content area will be nice.
