I just realized I hadn't done something like this before and well, while I dont often get nor expect giftart, I felt it would be a good idea to lay out my comfort zone with each of my charas.

Any form of clean art with all of them is not a problem at all!

Shuki/Ku, my purple haired lady, http://www.furaffinity.net/view/7398175/ whether in anthro or human form is fine to do tame or mature art with as long as it's solo. For risque pieces with another character please seek my permission first. Chances are it'll be cool as long as we're friends and the subject matter is something I approve of.

Aibreann, Shuki's mother, http://www.furaffinity.net/view/6695817/ is unlikely to be featured in any adult art at all. I would prefer that at least for now any depictions of her remain clean or tame.

Bligh the Selkie http://www.furaffinity.net/view/6907608/ is available for anything as long as it's with a lady.

Melita the Squee princess http://www.furaffinity.net/view/7939797/ can be depicted clean, mature, m/f, f/f, whichever.

Solitaire my kitty girl http://www.furaffinity.net/view/7639647/ is pansexual and also open to partners outside the gender binary.

This list is not exhaustive and will be added to. Also, it works on the assumption that no depictions will have fetishy stuff. If you're interested in any of that with my characters please ask first.
