Rough storyboard/ Proposal

I'm planning on doing an animation, most likely a hand drawn piece edited in photoshop. The idea behind this animation is to take the simple lines of clearly distinguished objects and, using those same lines, create a different scene.
We begin with a tree, it rotates, revealing a girl on a swing. We zoom in to the ropes of the swing, which become tracks, panning up to reveal a train. Finally we zoom in to the smoke from the burning coal and are again submerges in the same lines that represent tree leaves from the opening frame.
