>>17210anatomy-wise: it's like standard "how to draw manga" anatomy, but the limbs tend to be pretty long, mostly the legs. if you don't know how to draw hands it's ok; their hands tend to look like sausages. the anatomy is also slender.
the color palette is quite muted. the shadows are complemented by darker colors, especially on the skin and clothing.
coloring the hair works if you use an airbrush and then blend the shading with a specialized brush. kei-style shading is based on this technique as well; blending it lightly with the base color. there's a game released in 2009 called NUGA-CEL! where kei did the art for it; it could work as a reference for study, since the art is very similar to the one they would do for cryptonloids.
