You can see his teeth through his cheeks! The act of smiling is a bit odd for him... (although he would most likely be used to oddness).
That's the only decent screenshot I've got floating around at the moment, but there shall be more to come. Basically all of my Sims are ugly in some way. Today I made an ET-lookalike (...sort of)! And some of your creations I've checked out in the community are simply priceless. XD
Is there nothing better than sitting at the computer and creating ugly, ugly creatures?
