Art Trades: If you would like to do an art trade, email me with a link to examples of your art. I will reply if I would like to do a trade. I'll wait for your half before I do mine(to avoid getting cheated).
Gift art: As long as its not anything sexual you don't need permission to do gift art of my characters.
Art use: If you want to put my art up on a website, you need to email me and ask and have a link back to my site on the same page. Do not add my art to the site until after I have approved.
