Nice work David i have the d200 and do alot of timelapses myself. a couple of things that i learnt from working on survivor and seeing some of the best timelapses in the world from the shooters on the show is that 1. try not to get trees in your foreground they end up being to shaky. 2. use ND filters to cut down light and use slower shutter speeds to get smoother looking footage. I like the Moco action to your timelapse. look up paulo castillo time lapse crane. he is the best in the world IMO.
