The first reveal of a non-CGI alien creature from the planet to Tatooine made a cameo appearance.
Even though this is just a background alien character, it gives me hope that we will be seeing more costumed and puppet alien characters in the new Star Wars movie. George Lucas made a bit of a mess of things in the prequel films by filling them to the brim with CG animated characters. Abrams seems like the kind of director who would use CGI in moderation, though.
