Selling the stickers you make of these is considered commercial use and a $5 commercial fee is required. Art credit is required the first time you post/use them in a video or social media but that's it, as it gets old fast. Otherwise, feel free to do whatever you like with them!
Short TOS: unless the commissioner specifies otherwise, I have the right to use the art I make for them as examples in the future. You do not have to use these for telegram stickers, feel free to use them for discord, twitch or even make real stickers out of them 1/2
