Freestyle Football 16-Step Action Poster

Please generate a high-quality, high-definition poster-style storyboard for "Street Freestyle Football · 16-Step Action Breakdown." The layout should be a square 4x4 grid, with each cell showing a consecutive action step of the same street football performer in the same setting. The entire image should look like a combination of a high-end sports poster and a technical breakdown instructional board, possessing both visual impact and a clear sense of movement explanation.

[Overall Setting]
Theme: Street freestyle football performance (not a match or drill), where one performer completes a continuous set of tricks.
Atmosphere: Street vibe, urban, cinematic, athletic, cool, and rhythmic.
Background: Set in a nighttime urban small street pitch or city square football space, with graffiti walls, wire fences, distant building lights, street lamps, and slightly reflective ground. The environment must be consistent and have a trendy street aesthetic.

[Character Requirements]
Protagonist: A young, handsome male freestyle football expert with a light, coordinated, and athletic build, short black hair, confident aura, and fluid, controlled movements.
The same person must appear in all 16 cells; do not change the person per cell.
Outfit: Cool-looking football kit, but no words like "Champion" or specific country names. The clothing should feel like a professional team jersey.

[Layout Requirements]
The full image is a 4x4 grid of 16 cells. Each cell must contain:
1. Large step number (1-16)
2. Chinese action title
3. 2-4 brief Chinese action points
4. Clear full-body action shot of the person
5. Football trajectory arrows / footwork paths
6. The ball must be clearly visible and logically positioned.

Overall font style: Sporty poster aesthetic, clear and powerful. The image should be sharp, clean, and the person and ball must be complete, not cut off at the feet.

[Action Sequence]
Please design 16 continuous actions in order, each distinctly different, forming a complete freestyle routine: [Detailed steps 1-16 including Starting Pose, Sole Pull, Stepover, Flick-up, Knee Control, Around the World, Shoulder Stall, Rainbow Flick, and Final Bow].
