Nice setup. I think the lighting is a little flat in this shot though. Some front or side lighting might add some warmth to this shot and make it more appetizing.
Beautiful shot, but the product isn't the "center of attention", and the upper edge of the label is out of focus. For advertising, the props must support the product, not the other way around.
Not a bad effort at all. The cheese and crackers look tasty (it is hard to photograph food well). I think the knife was overduing it a tad. The viewer knows how that one slice of cheese got there and the knife doesn't add anything aesthetic to the composition. It actually leads the eye toward the napkin in the background.
