Good, but needs a few improvements..
Firstly, I thought it was quite good, I think the style you used was original and suited the content well. The drawings were very good also.
A few issues that you may wish to improve upon as you progress with Flash would be firstly the use of a preloader and play button. There are quite a few tutorials floating around and there is even a Newgrounds premade preloader for use. Secondly, please, for the benefit of loading time, learn to compress the sound files you use to a lower bitrate (you can do this through the Library, and going into properties of the music file and changing the bitrate to something like 24kbps). This will dramatically help to lower the overall movie size, with not too much of an effect on the sound quality.
There will no doubt be some criticism of this from the reviewers, try to take some advice out of it rather than insults.
Overall I thought it was very good for a Flash 'noobie', all the best for your future movies.
