I post thumbnails of this submission on my Character Sheets to quickly show in a relatively eye-catching way how erotically I'm comfortable drawing that character myself. (Sometimes I change my mind.)
If you draw one of my characters outside of their listed Content Rating... well nothing really happens. I don't really care, other than that I won't publicly acknowledge it other than removing it from my own pages if somebody posts it there.
Anyhoo, the ratings are:
Golden rule: No exposed breasts, butt-cleavage, buttholes, boinkers or bollocks
Clean art is devoid of sexual implications, to a point. Admittedly, many of my characters are unable to pull this off.
Female characters can be well-endowed to a considerable extent and still be considered "Clean". However, at a certain size this essentially becomes "hyper" and Clean is no longer feasible.
Golden rule: No arousal or huge naked privies
Suggestive may contain either a sexually suggestive posing or situation or nudity (defined as visible bare boobs / buttholes / private parts) but not both because that would probably be a pinup which is Softcore.
In general, characters who are showing themselves off in Suggestive work aren't intending to do so. For instance, an innocent girl might lean over to rummage through a treasure chest while the viewer checks out her ass. (She has to have some kind of leggings on or this is Softcore.)
Sufficiently well-endowed characters like Meadowbreeze are more likely to look naturally suggestive or enticing while naked, gravitating them towards Softcore where a more petite character would be Suggestive.
Golden rule: No sexual contact (masturbation, intercourse)
Pinups and suggestive nekkedness, but not sex.
Contains most content too explicit for the above categories, including masturbation or humping.
In general, please avoid alternative fetishy stuff unless the character is already clearly connected to one and/or it's mentioned in their bio. Thanks a bunch!
