I love all the details showing here, for example, when Han asks for water, he said it in a small voice, which helped me to see his awkwardness. When Storm trooper bends Vader's straw, which helped me to see Vader's silliness not only helping me to believe it's real.
I think there are two merits when we show details in animation. One is that audience believes it's real (as material or character) and another is that audience understand the character's feeling, emotion. What do you think?
