The document discusses the author's progression from the preliminary task to the final film project. In the preliminary task, the author's skills in editing, camera work, sound design, and use of mise-en-scene were more limited. However, for the final film, the author gained experience that allowed for improvements in interesting camera angles, subtle audio layering, continuity, set design, costume design, use of props, lighting techniques, and cinematography. The extensive reworking of drafts also improved the overall quality and coherence of the final film compared to the preliminary task.
