JJ Abrams has been all over the secrecy aspects of Star Wars: The Force Awakens, namely keeping things a secret. According to Indie Revolver this is a leaked concept art photo of Supreme Commander Snoke.
Snoke is supposedly the new big baddie in the Star Wars Universe. Now, take this as a rumor and nothing more. This has a high probability of being true, but until it is proven to be that – it’s just a rumor. There is also no word on whether or not this is the final concept or it has evolved.
