Since creating their preliminary task, the document's author feels they have improved in three key areas for their full opening sequence project. They went from basic filming and editing skills to becoming more experienced with techniques like clever camera work, editing effects, and purposeful mise-en-scene. Specifically, they planned locations and costumes more carefully to set the right atmosphere, used more complex shots like high angles to build tension, and incorporated editing techniques from popular thriller films to keep the audience engaged. Through further practice and studying other films, the author and their partner enhanced their skills and created a stronger final product than their original preliminary task.
