I've been told that the Model Viewer program may be "technically against the Terms of Agreement, even if it isn't an in-game thing," so I won't encourage you to download it. I will, however, warn you that fake versions are floating around with viruses in them, so be careful. If you decide to get it anyway, do so from the creator's site.
Now, this is a photo of all of the characters I have, would like to have, or will make my husband have. (Guess which one he gets? ^_^) This is just some fun character design. You can recognize two, I bet. And if you want to, go ahead and guess which ones are from the character profiles post.
