Um... I don't think it's something special. For Chrysalis, it's very easy to paint her like this. You don't need a lot of fancy colors, just shades of gray. I just paint with darker gray where the shadows are, and with lighter gray where the light is. Then I blur a lot to get her silky smoothAnd add some color highlights (blue and green on this picture) on a separate layer in Screen mode. I use airbrush for the soft highlights, and the usual brush or even pen for the sharp ones.As for the hair, it's pretty long to explain, I have a tutorial here [link] It is in Russian, but I hope you can understand some basic ideas from the pictures or with google translate, it's not very hard, really.
