Some of the contest submissions kinda got confused on what BE is, so... made this little visual guide to help out.
If your submission falls into the "not BE" category, please don't feel attacked or something; I just wanted to provide some advice for distinguishing BE.
I'd often think that drawing an anime character that normally has small boobs with large boobs was also considered BE, but thinking it over, that would only work for people who knew said character. Other than that, I totally agree with this.
