The music corresponded with the visual images very well. The music really helps to carry the story and provide some feeling into anyone that watches it.
The timing and choice of visuals displayed were chossen very well. The whole storyboard seemed pretty good. The fading into other moments showing the connection between the Robot and Inventor, was a very good technique and worked.
The ending lacked some resolution for me, the story didn't seem complete. I definatly felt something watching as it progressed, but didn't get that same feeling at the end. I do like the little animation on the end though of him shaking all nervous, heh.
Overall it was good.
