The student learned several important lessons from receiving feedback on their film trailer, billboard, and poster:
1. Camera work needed to be steadier to appear more professional, requiring re-shooting some scenes.
2. Background music volume was too loud and obscured dialogue, so it needed reducing in editing.
3. An opening title and title cards were needed to add context and meet industry conventions.
4. Shots in the trailer were too long and needed shortening to improve the editing.
