welll......... face it....
ok first off ever thing he has said (the guy bellow me Zedd56) is very right on ever thing i will break it down a bit more ... speed up the frame rate your fps... obviously you can do this cuz you not on 12 fps ... i would say in between 22- and 24...
if not higher you just have to make the movements a bit closer, use the onion skin it is very helpful i never know about it untill i hit it, its on your time line use that its such a help for newer animators but really the main thing you pretty much took an idea that someone had already come up with and compared to this, this sir is crap.
come up with a main character, story line,blah blah blah... another tip for you think of physics and physical movements.
you have the art work skill to make a nice video if you take time with it...
g\l on future projects.... xWRx
