This is the identity I've created for Planet Tatooine, from the Star Wars franchise.
The flag: the flag mimics the sunset in Tatooine, a desert planet with two suns (see the image taken from the movie for reference)
The crest: the crest is based on the flag, feature the two suns and the colours of the Planet. It also features the inscription TFA (Tatooine Football Association) in Aurebesh, the in-universe alphabet.
The jersey: the home jersey for Tatooine planetary team is primarily yellow, with light and dark blue details. In the inner collar, there's an inscription that reads "Tatooine", again in Aurebesh.
USL logo: this is a simple logo I've created for the league, with features a ball and some stars.
