It doesn't even look like it's ON the paper! It looks like it was photoshopped onto the paper! What kind of pencils are those? I know regular colored pencils can't possibly work THAT well on ANY paper! They always show the paper texture underneath.
Can I have a question? Because I pretend to similar style of 'cartoon' traditional art with polychromos... do you draw the lineart twice? I mean... polychromos have strong opacity and they cover black lines. Do you draw them again over it?
