3:The sim you're sharing is a toddler, child, or teen, and your upload does not include any pictures of what the sim will look like when they grow up. It's okay that you haven't shown them older, but perhaps consider aging up your sim and taking a picture of what they'll look like older. It's okay if they're weird looking, but it's nice for downloaders to know how a sim will look when they grow up.
4:You have included one or more pictures of your sim grown up, so downloaders will have a good idea of how your sim will look when grown. Nice!
5:You have included one or more pictures of your sim grown up, and your sim looks quite good when grown too! Well done!
