Hi Kelly...no advice on pricing (I'm struggling with mall pricing myself). But in my opinion, the background is too light for the dress. It just doesn't pop, and I have to study the picture to separate dress details from background. I'd try it with black. Or maybe someone here can tell you how to change the background color in your photo editing program so you won't have to re-shoot.. Again, I can't help you there bacause I'm still struggling with that, too..!
