One of the ones he saw was of Theed, the capital city of Naboo. He also attached a custom photo of the scene he saw. The entire film is complete, in rough edit form and looks incredible. Watto doesn't float, by the way. Having seen him in a scene on Mos Espa with Liam Neeson, he flies.
H e looks like a giant mosquito with a beak.
As for the rough edit scene attached, it is completed and features Theed courtyard and hanger, overlooking a waterfall. But of course it will all look like one location. I assume it's the moat. The sub set-piece which I have seen was placed in the water for them to jump off. Well, compare them to the flowers growing up the walls on the Leavesden set and you'll see that they are meant to be the same building structure and style.
