been talking about this a lot lately, but the talent Studio Giggex has shown off in the last few weeks is a rarity in the western world.
so the method they used for the Shadow shorts is 2D animation on top of 3D models, they're penciling in the faces, particle effects, etc on a frame-by-frame basis. this is less like Spider-Verse (which was 3D animation with 2D effects) and more like Iron Giant and Prince of Egypt. this shot of Maria turning her head is practically impossible in anime because you can't have both a good three-quarter view and side view, but here it works perfectly.
i really hope Giggex sticks around. this is a long-abandoned style.
