Living in lower Westchester, I visited this castle for a Lego event that was being held there two or three years ago. I didn't immediately recognize the builder of this work, but upon finding Chichen Itza and Independence Hall I immediately realized that I had previously seen them in a certain Brickshelf folder. That was fun, even if the event itself was targeted at children much younger than I.
This Castle has been done very well. The best part of it is your use of unusual parts. The droid bodies, Technic parts, joystick peices, and so much more. If you want more feedback you should try posting it at LEGO and more LEGO (laml.proboards3.com). P.S. Is it yellow in real life?
