This could be a better shot with more lighting. Most product shots try to reduce shadows by throwing multiple diffused light around - removing or reducing the shadows significantly (check out the almond bar photo in this contest - not mine). Also - I don't know how healthy those bananas look - I would have gone for more complete yellow to get the concept across.
excellent idea ! people gotta make that choice. the only thing you can do little better in this picture is that the banana, which is supposed to be the choice of being healthy, dosen't look so healthy. a good picture for the topic any way !
