This is a brilliant piece. Your use of light shows the characters in their natural state perfectly - the Doctor cornered in the last ray of light, standing defiantly in front of two cowering figures, and Darth Vader striding forward through the shadow with actual mist curling around his ankles as if he's in a horror movie. The fact that Darth Vader is significantly taller than the Doctor adds to the feeling of desperation.



I kinda feel duty-bound, as a massive Doctor Who fan, to correct some myths about who would win. First of all, Time Lords are not immune to strangulation. They have a "respiratory bypass" that allows them to take in oxygen without breathing. Having one's neck crushed is an entirely different matter. Also, a big part of Eleven's character arc is that he's old, weakened, and inexorably nearing death. He's on his last regeneration, running out of both energy and clever tricks. I highly doubt that the Doctor will die here, but that's only because his appearance on either Lake Silencio or Trenzalore (depending on where he is in the timeline) is a fixed point. I also completely expect that he has one last trick up his sleeve to get the people he's protecting out of there. (Maybe he'll remotely land the TARDIS around them?) But against a fully-fledged Darth Vader at the height of his power, there's very little else he can do.



Knowing that gives the scene so much more punch, too. You can see the Doc, like I said before, cornered in the last ray of light, defying Vader's power to protect two innocents, relying on a move that he must know won't stop Vader for long, as Vader himself advances along with the darkness and the fog. It gives the definite feel of a last stand against an unstoppable foe.



(Also, to respond to the critiques, I think the fact that the Doctor seems out of place is a plus, because, quite frankly, if the Doctor doesn't seem out of place in every scene imaginable... somebody's not doing their job.)
