My Minecraft Skin Was Taken Down?

For no reason, might I add. I'm a person who has her own style of shading, and likes to apply them to other people's skins and give them credit for the outline of the character's clothing. This one, however, was taken down for no reason whatsoever. I didn't break the upload rules, I gave credit, I even got the person's permission to make this skin! That's how much I don't want to spend ages on something and have it removed. But sure enough, it got removed. I don't understand what for, I made it from scratch as to avoid them thinking I stole it from someone else. I also went as far as making it in a different colour palette for them. I got loads of comments on my skin, all positive, then a few hours later when I went to check on it, it was gone from my profile! I'm glad I'm one of those people who likes to save things to the hard drive just in case, but I still lost all my views, my toes, and my praise. Can anyone give me any reason? It was uploaded to "Skindex" if that helps, too.
