After Effects

I have changed my mind about doing my animation 

with stop motion animation, because all though it worked

quite well, it didn't have the effect that i want it to,

i can't get the motion smooth enough, and this doesn't

work for the beginning of my animation. 

so i have decided that i will use after effects
so that i can pin all of the points of the tree and make
it move fluidly and also so i can make the leaf follow
a path and not have to do it manually.
