I have tried to find pictures like this, where there is a girl floating/falling with their eyes closed in a dramatic, moving pose like the one of Ryougi Shiki I posted above. I can't find any good ones. Please let me know if you can find any!

I remember there is an image like that in Disney's Atlantis, although technically that was a girl floating up rather than falling down
Here's some fanart of that scene to give you an idea, or skip to 1:10 in this video.

And Hatsune Miku is often drawn like that, for example here, here, here, and here.
