The author learned several important lessons when progressing from their preliminary task to the full product. For the preliminary, they focused on dialogue-driven comedy but realized the script was weak. They also used a limited number of shots. For the full product, a horror film, the author removed dialogue, relied more on visuals and score to build tension, improved shot variety, filmed at night indoors for lighting control, and learned editing techniques to make filming more efficient. Overall, the author gained valuable insights into script/dialogue quality, shot design, and production/editing workflow.
