The creations in Star Wars are a culmination of dozens if not hundreds of people's work, but I don't think there's anyone who would disagree with calling them George Lucas' creations simply because if it weren't for him, none of it would have ever been possible. No one would have had the courage to create these iconic designs and bring them to life if it weren't for George paving the way, despite everyone telling him it was a bad idea. That's why we can call George Lucas the father of Star Wars, even though many have contributed to its success.
It's eerie to see all those creations surrounding him. It's like they're swallowing him, which is a metaphor for what Star Wars has done for his life. Even after he's sold the rights to Disney, he's still surrounded by his creations.
