I downloaded it and saw it in QuickTime with no problem. It's very jumpy because of my low RAM, but I went through it frame by frame: it is absolutely gorgeous. Well done erwinraaben.
One thing I noticed is the epeated use of birds. They're up in the sky when the Salamanders are looking down at Stranger, they're there again when we see the Natives from high above, they're scooting through the graveyard in two different shots... There is even a small fly that passes the camera before Stranger slams the wanted poster on the desk.
However, I did notice that the Clakker does not actually hold the stamp: it is suspended magically on the feathers. *sigh*
