Honestly, I am not entirely sure.
I did sent out more than 30 requests during my daily sculpt period before I stopped it and only received a few back.
After that, I sort of lost track.

I've only ever had one request to take down an image due to lack of permission and is a reason why I now choose Japanese artists instead of anyone on Furaffinity, InkBunny or even Weasyl.
They love it when I sculpt their characters, others are very finicky and get upset or have egotistical issues, which is the very opposite of what I am used to lol

I can change the colors and modify a bit it so the character doesn't look like yours if need be and also change the name.
