'Slap' first outcome

Untitled from Ryan Tailby on Vimeo.

This was my first attempt at my 'slap' piece, having researched into the word this was the outcome i had. the 'S' comes in it starts big and reduces in size making depth into the piece.
i believe i used anticipation well on the 'S' it starts slow coming in and gathers speed and then has the impact of the slap. for me the staging was an issue. How would I start off the 'lap' without giving the word away and breaking the anticipation, so i placed the words in front of each other like so and reduced the size making them appear on a side ways view so when the 'S' comes on screen and slaps them they would react and rotate spacing out revealing the letters.
i studied how a face would react when slapped and i attempted to create something similar with the 'l' and 'a' i stretched them to give them the effect of dragging along with the 'S' i believe i could have done this a lot better but for my first attempt i thought i captured the motion of slap rather well.
