Hard to be original with dressups, so its nice to see a totally new subject to dress up. It all works fine and there is a lot of choice, with good looking and creative options. The music is nice, though nothing particularly romantic or inspiring.

what would really make this if it had some way to send itself as a selected image to one's loved one. I don't know if that could be programmed into it, but if I could I would make one of your e-cakes and send it to my beloved!
