Demon wings help

Anyone seen any good demon wings for a full back piece lately? Need ideas to play with... Did internet searches for it and didnt come up with much, thought the people here might remember seeing a piece/drawing/reference or two. Thanks, Cain

it might be kind of cool to do really pretty angel wings on the demon.. its kind of biblical that demons didn't lose their form when they were cast out of heaven and so they still look like angels and if you were going for a biblical kinda theme that would be original
