Joshua Viers is a senior illustrator and art director at Industrial Light and Magic and he sent to /Film these beautiful Star Wars concept art! The illustrations were not done for Star Wars Episode 7 but for fun, so don't expect these scenes come to life in any future Star Wars films.
The above first concept-art is called "Empire Bargains," and the scene was inspired by the one below, a famous scene from Sergio Leone's western Once Upon A Time in the West. Joshua Viers said that “Lucas was inspired by Leone’s work for the original films, and I wanted to recapture that."
Below, more concept-art from Joshua Viers, make sure to click on each to see them in big size.
