You are free to redesign or rewrite any characters that you own.
You may not use my designs in any morally wrong or hateful content unless in a specified story setting.
You may use my designs for commercial products as long as you don't take credit for them.
If you are reselling a design, do not overprice it. The only things that add to a design's worth are commissioned or personal creations.
Co-owning is allowed. Do not involve me in any character-related drama.
