I agree with having a little more color/contrast in the background. Also, I like the 3rd pic better than the first, because it is less about the box and more about the actualy product, yet has the extra little splash of stripes to hold interest. maybe you could show just one "candy" by itself for a size and composition reference?
CleoHalfpenny~ I really like the last pic with the necklace in the doll's lap, maybe you could brighten the photo(s) and crop in on the last one for your 1st photo. That way there's less empty space in the thumbnail when the potential customer is scrolling by....less dead space, more interesting/coordinating pattern.
Here's mine:
