In comparing their preliminary task to the final product, the document discusses several key areas of improvement:
1) A wider range of camera shots and movements were used in the final product compared to only a few stationary shots in the preliminary task.
2) Better understanding and application of techniques like shot composition, the 180-degree rule, lighting, editing, and shot reverse shots improved the flow and engagement of the final product.
3) Valuable lessons were learned around efficiently incorporating different shots and camera movements, adhering to filming rules, and ensuring shots flowed coherently through editing.
