If you're looking to get a commission with him involved or draw any fanart I'd like to say I'm honored and it will be very appreciated, but I would like to mention Non is very much a sona to me and I have a few things I am adamantly against him being involved in:
1. Vore — I know he's a tatzlpony and that's what they're known for but I would really prefer Non not be involved in vore or activities hinting at or related to it (scat/digestion/anal vore/unbirth etc). He's meant to be a happy goof and it feels incredibly out of character to me, plus I'm really not a fan of the stretchyness required for the acts. I'm in no way insulting these kinks I would just prefer not to have my OC involved.
2. Gore/heavy abuse — Same vein as above, with him being so happy/carefree I would prefer not to see him heavily abused or injured (cool with submissiveness and slight roughness but nothing excessive/permanent). Him doing the abusing/injuring is also waaaay out of character.
Anything else can be discussed and I'll probably be ok with it <3!
