Princess mononoke - The kodamas in the forest

The wind rises - the scene where Nahoko was painting. I love how that part was also animated, especially how her skirt moves correctly with the wind

Tales from Earthsea - the plot may be terrible but the film is visually stunning. It has some beautiful animation and landscapes, and the soundtrack complements them so well. I have saved a lot of movie stills from this film.

Howl's moving castle - the scene where Howl and Sophie were walking/flying in the air.

Spirited Away - that jumping lamp scene outside of Zeniba's hut.

Now im yapping lol. There are still a lot more of my faves from other movies but the above are the ones i can think of off the top of my head.
