Looks great. It'd be better without the ad, but what can ya do?
Maybe try moving the ad to the bottom, and moving it all up, so that Caves of Narshe is next to the circle pic, but I don't think that'd look right. I would move the ad, and make some kind of collage, that interacts with the gray bar (or not, it'd look good either way), and place the collage where the ad is....yea, well there's my 2 cents. I think it looks very professional though.
