Hello! Thank you for taking one of my likely unused designs! I have a few terms for you to look along once after taking in an overly idle character.
1 - You may change the design as much as you like IF it is on a base. If not, when redesigning please try to keep it the same.
2 - I put a lot of work into them, and it would be preferred if they find of no use to send them back to me in an attempt to give them a better home!
3 - Keep the same value of them if you want to resell them, if they were free, they are free. If they were from a raffle, they were free. If art comes with them you could add a bit of price rasing but it not of best heart to me.
