Figure Skating

Competitive figure skating live performance. Opening with a low-angle shot following the skate blades gliding on ice. The female skater wears a deep-blue figure skating dress. The full sequence delivers a complete narrative from tense mistake to calm, successful execution.

Wuxia Battle

A Wuxia-style audiovisual blockbuster. A white-clad swordsman and a straw-caped blademaster face off in a bamboo forest. The camera slowly pushes in between them, shifting focus between raindrops and sword hilts.
