So professional animators and animation tutorials (more often western) always emphasize on how important it is to keep your characters simple and break them down into simple shapes. As someone who studies 2d animation every project makes me realize the importance of this, even the most insignificant detail on a character can become a pain in the ass to redraw multiple times. However, in anime characters will usually be quite detailed (for example,for hair larger shapes will be apparent but there will still be many individual strands). How do japanese animators consistently animate characters that are way more detailed than most western stuff?
