𓆃 Ideya Garanina - Crane's Feathers (1977); َA Russian animation based on a Japanese folk tale
i have a soft spot for "swan maiden" stories! these adaptations use the same medium [stop motion animation], and even very similar color palettes, but their approaches diverge (especially with the sound), giving each take a different emotional tenor and texture. i love both and invite you to compare and contrast!
