@NoDoxGregBrady Lucas has great visual taste. He isn't an artist himself but he has his artists do hundreds of sketches and paintings and he picks out the ones he likes, maybe asks for a combo. Or a concept model that can be fine tuned. So the prequels are full of great looking stuff - Darth Maul, super battle droids, Coruscant, the Senate chamber, the cloning facility, Theed City on Naboo, General Grievous, Amidala's chrome starship, and of course the clone troopers. Not to mention the spectacular volcanic backdrop for Anakin and Obi-Wan's penultimate battle.

It's hard to name a character or location from the prequels. BB-8 and Kylo Ren are about it... and Kylo is all Adam Driver's performance, his costume is terrible.
