This is a pretty vector, but there are two things that I didn't like about it: - The exclusive use of black lines--none of the lines are colored, even a little, so they stand out in stark contrast in light places like the skin and hair - There is no variance in width with the lines, which robs a lot of the emotion from the piece.

Like I said, it's pretty, there are just these couple things that could be done to make it even better :)
