Agent John Smith's Ownership

Don't resell for egregiously more than you paid (incl. art, writing commissions, redesigns, etc.). You can up their price some if you have done lots of art of them, or if someone offers more than you paid you can accept that. As long as you're using common sense and acting in good faith, you should be good.

Once a design is yours you can use it how you want! Make it your fursona, modify it, make it a character in your story, trade it again...
(I doubt this will happen, but just in case: Please discuss with me first if you plan on making it something like part of a company logo, or anything to do with incorporating it, especially if you would be making a lot of money off it.)

You don't have to credit me every time you use/draw them, even off-site, but if you do upload them to another character banking site you can credit me here (ThornShadow on Toyhou.se). If you (or someone else) redesigns them please keep me credited as the creator/original designer but you can totally add other designers.

You may not use anything I have created in NFTs or crypto-currency.
