Choose an overlay sheet and draw the first scene, then trace it into your script with the support of a spotlight. Once finished, add the overlay sheet on top of the first one, draw the second shot or second frame and repeat the action. The more you draw a scene, the better it will look, that means that at least one frame per second will have to be drawn, except for some actions. For example; a punch can skip five frames from one shot to another.
Experience will teach you many ways to use this technique, do not hesitate to investigate and there will come a time where you will not even need acetate sheets for your animations.
