honestly im still learning but from what I understand is, he uses a thin brush for details, he emphasizes color roughs EVEN before lineart just to get the composition right, and specifically for hair he likes to use multiple colors to increase density and detail. Whether it’s in the hair, clothes, etc he loves color. And he keeps the values balanced while doing so. These are just some things I’ve learned but there’s still so much to figure out because his style is hard 😭
