One thing that I think is a bit understated but still important in Star Wars is the feeling that the Galaxy is a large place. There are countless alien species, places to go, and as mentioned, they're all so very large in scale. Places rarely get reused without reason (Jabba being the unifying factor in Tatooine in the original trilogy - let's not speak of the prequels and how the planet was somehow so important to everything), and there's always somewhere else to go, something else to see.

The Galaxy in Star Wars should be painted in vivid colors and large scale. But, at the same time, each location works their own narrative purpose that is rarely ventured beyond. In a sense, planets in Star Wars have the same purpose as cities or nations in other settings. The distances and scale simply differ.
