Well the fact that I had to give it a good look to determine whether or not this was Cosplay or Digital art is probably an indicator of just how good I think this piece is.
The costumes are strikingly accurate, as well ad the meticulous attention to such little details as the set of your shoulders and the composition of the shot. I don't know if the placement of your fingers was deliberate but they were one of the reasons I really couldn't tell if this was real or animated.
Maturally, the post production on the shot matches the movie perfectly and creates a suitable surreal atmosphere, but as far as the modeling components of the shot, I say stunning.
Very very good job. And I think any and all fans of the movie will appreciate this.
