How is this work not good enough? Is it because it isn't in drawn in manga style or something? From what I have seen of the artist's other work he is decent enough with various art styles. So I am kind of unsure exactly what here is does not meet the standards Danbooru has.

Could someone elaborate why this doesn't meet the quality standards whilst stuff from rakugaki-biyori gets through scot-free? Not that I want any of their stuff removed, but it would still be nice to know why this image isn't good enough.
