Eh....
This needs allot of improving. It's a bit too jumpy, parts went either to fast or (more commonly) too slow. I haven't seen the original and I think I'm glad I didn't. It sounds like you improved, but my second flash movie (when I was 11) was better than this. I suggest you leave newgrounds for a few months and practice making flash. Look at some tutorials around NG.
For this movie, (if you ever remake it) you should add some SFX and make it longer.
