This looks nice! The generated images are pretty crisp and lifelike. The name is quite catchy, and so is the idea. However, a quick suggestion. It would have been great if you had added some context about the product on the homepage. That way a normal visitor, who has no idea whatsoever about ArtHeart, can be converted to a user. Nonetheless, this looks like a pretty fun app to try. Congratulations on the launch guys!
