Disney has released even larger sized images of Supreme Commander Snoke and Maz from Star Wars: The Force Awakens.
In addition, a Redditor has manipulated the color of the Snoke image, which offers an even closer look at the big bad's features.
You can also check out video about the theory that Snoke may actually be Darth Plagueis.
And here are the official descriptions of the characters:
Supreme Leader Snoke
The Supreme Leader of the First Order, the mysterious Snoke has no permanent base of operations, preferring to contact his underlings from a mobile command post. Snoke is powerful with the dark side of the Force, and seduced Kylo Ren into abandoning the Jedi path to become his apprentice. But Snoke also commands General Hux and the technological war machine the First Order has engineered to destroy the New Republic and Leia Organa’s Resistance.
Maz Kanata is more than a thousand years old, a diminutive being with vast experience at surviving in the underworld. From her castle on Takodana, Maz has seen galactic powers rise and fall and felt the Force ebb and flow, seeking an elusive balance between darkness and light. She has given many a young smuggler a start by offering credits, equipment or connections, and helped many an old friend rediscover a lost path.
