not bad for a start
seems you have 2 MAIN problems. . .
1st is that you lack in lining the sprites up. (dont worry im not trying to be mean)
you can try what i do sometimes. Make a new layer called Guide and not only do you make a bright, thin outline around your work space(the hole square) also make a line for where everyone stands.
2nd your fps. Im not sure if your doing to much than what you have to, or you have the fps to low. Mine is 15 fps lol i like it that way. looks like your using 12.
try setting it higher OR just stretch the movements out on each keyframes.
but it was good enough to watch ya no? so im giving you 10
