Here's the trait suggestion thread. It's best to put your ideas in there so that all the suggestions are kept in one place and are easy to find. Also the admin will sometimes make a contest out of trait suggestions for upcoming large fests. I recommend participating in those to get your ideas seen. You'll need to draw your suggestion on a blank pet. It doesn't need to be a perfect drawing, don't worry. Just enough to get your idea across. They'll be relined by the site's artist anyway.
