well,i gave it a four
you really need to work on some easing and physics
ill give you an example
on your easing make sure that you start off by
slowy moving the joints,then gradually increase the spacing in each frame
wants you think you went fast enough,make sure you slow down the movement of a joint
each frame
the way your easing,if you wrote it out would look like this
--/--/--/--/--/--/--/--/--/--/--/
and the way it is supposed to look like is this
-/-/--/---/----/-----/------/----/---/--/-/-
good:
bad:
can you see the difference?
