Not bad. Styalized but missing the message.
One thing I can point out for when you do your next flash movie: The robot's arms were swinging the wrong way. When the leg goes back, the arm goes forward -- like the way people walk, otherwise it looks strange.
And I did get the impression of lonliness from the movie. But I don't think it quite conveys what your description is trying to illustrate.
The quality is good though. This should set the bar for new animators. Anything below this standard is people dicking around (who should be impaled). And your audio is the best quality I've ever heard.
