I give you a 7 for the effort, very nice, but their is alot you missed.
For starters you don'r have enough imbetewwns, their should be about 6 diffrent frames for each leg in your walk cycle. in other words your walk cycle should be around 12 frames in total, also make sure you set flash to play at 24 or 30 frames per second.
Also you missed out on a lot of the rules of animation, if you want to become like a disney animator you have to master theose 12 rules. if you don't know them, please look them up and learn them. once you do, you'll learn your animations will take on a whole new look and level. also you missed a delightful chance for accents.again refiring to the 12 rules.
and your music choice was ok, but you should have goone with somethign creepier and with not lyrice. some sort of ambiant music would be best. also look in to some good sound effects, step sounds would have enhanced the over all feel of the animation.
Now on a good note the animation some what did well with your backround and ran pretty well. likie I said, the effort is their but you lack knowlege, once you gain that you'll be animating in top notch in no time.
