No, I don't mind, and nobody else will either.
So feel free to post your works there, Nerdy. I will post my stories and art soon, too, I have just been busy adding so much to that place. Anyway, here is this image that you can use, but if you feel like making an extra one of Hyrule Castle, I can surely use that one for another skin too. Btw, add the name of the site to it. I won't mention it here to you for privacy, but you get a good idea of what that is, right?
