If you snap your own fingers, notice that there is a recoil that can stylistically be animated with a well-done motion blur. Not the literal blur, as in the filter, but the old-fashioned blur, done with drawing the hand with a collection of lines that are all pointed in a single direction.
Maybe you could use no blur at all, but keep in mind that there is a recoil, and a smaller recoil to that recoil.
