My two-rule copyright/commission/whatever policy if you ever decide you wish to use my work for anything.
1. Give credit. It doesn't matter if it's in the form of the title, the description, the tags, etc. as long as you name one of my art profiles.
2. If by any chance you make money due to my work, such as if you sell my art for money, make a video with it in it that gets money, etc. then take only the money you need and give the rest to people in need. I'm sure the area you live in has plenty of those.
