:D Yeah. I've had that problem before. It's against the rules to use any textures or skin parts you don't have permission to. I had a skin taken down because the texture I used for a small portion of the arms was a totally recolored texture from another skin.
Following the logic of the PMC, unless you emailed mojang and got signed rights to use it, you really shouldn't. xD
Plus getting your account moderated results in a two day ban from pmc. Can't upload, can't comment, can't use fourms.
