Li-Ning sneaker particle light effect launch poster AI Image Prompt

9:16 vertical cinematic fashion photography style Li-Ning sneaker new product launch promotional poster, surreal particle light effect matrix. A Li-Ning sneaker floats in a pure black #030305 background space, in a side-standing pose with the toe facing right, entering the frame at a 30-degree angle from the lower left to the upper right, with the outer edge of the sole fully visible. Countless glowing particles flow precisely along the shoe's geometric structural lines, forming a skeleton of light: ground particles flowing along the outer edge of the sole are the brightest and densest, forming a closed halo trajectory; structural particles flowing along the upper's ridge line and hot-melt film bonding line are the thinnest and darkest, forming light meridians on the upper; occasional dissipated particles drifting outward from the sole gradually dim and disappear 10 to 20 cm away from the shoe. Behind each particle trails a short tail about 3 times the particle diameter in length, one shade lighter than the particle body, creating a time-frozen illusion of flight. Particle color temperature transitions from toe to heel: toe area warm gold #E0A030, densest and largest; mid-body neutral white #F0F0F0, thinner and smaller; heel area deep red #C01818, sparsest and smallest. The particle matrix is self-luminous, like sparks suspended in the air with a faint halo. A very hard golden-orange key light, color temperature about 2800K, comes from the right side of the frame at a low angle of about 15 degrees horizontal and 10 degrees upward, cutting an extremely sharp highlight strip about 2 mm wide along the hot-melt film bonding ridge, the brightest point in the image. A tiny LED fill light from the front left fills the eyelet panel position so that the Li-Ning logo on the shadow side also has visible detail. The pure black background has very faint deep blue mist in the four corners, like a stage vignette, pushing the gaze toward the center. The camera is parallel to the shoe's side elevation and at eye level, allowing the complete circular trajectory of particles flowing along the sole edge to be seen. Color scheme: pure black background + warm gold to deep red particle gradient + golden-orange highlight + very faint deep blue vignette.
