Dramatic low-angle tracking shot speeding along rain-slicked train tracks through a narrow mountain gorge. Dark rocky cliff walls rise on both sides, with overhead bridges and power lines crossing above. Moody overcast sky. The camera rushes forward at high speed. Two women, one with pink hair in all-black tactical gear, the other in a white bodysuit, fight on top of the moving train, exchanging martial arts blows as sparks fly. Dynamic action choreography, dark teal-grey color grade, cinematic speed and motion blur, sci-fi action film aesthetic.
