Nice man.
Comments before actual review - Ha, I was just sitting here relaxing and I clicked some links open from the RRC. I didn't read the flashes names and I just opened up this one first. I was like, "Damnnn this introduction is good, I hope the flash is good too!" And then it repeated.. and I was confused.. then I looked at the title and noticed it was just a introduction. >.<
Animation/Graphics - The animation was very smooth and the drawings were done very well. Great background and color choice. There really isn't much more to talk about in the terms of animation and graphics because it was done very nicely.
Story/Content - Of course there isn't a story behind an introduction, but I can comment on the content of the flash. This would be great for many Halloween flashes. It's a great introduction all around.
Audio - A very nice choice here. It runs very good with the animation itself and everything. I do recommend compressing the audio though because it seems like the audio is bringing the file size of this way up. If you need to learn how to do this take a look at this tutorial here.

Of course remember to remove any spaces which may be caused when I entered this in.
Overall - A very good introduction and the only thing that I can find wrong with it is that the file size is way too big. Hopefully the link that I sent to you can help you out.
