White board[i]ng, again

Good line work? I’ve always heard it as clean lines, solid, with use of gradients in value and width, and not overly complex, but those aren’t really anything conclusive.

What I like about yours is the character and quality that the line gives to the overall picture. There’s a mood to it that is playful, bold, sensual, and lively. Neither hair nor face are over-rendered with lines, allowing the subject to fill the space with ease and get the point across in clarity.
