为一部名为《霓虹巷对决》的原创高能动作短片创作一块垂直的单幅动画开发板。

Create a single vertical anime animation development board for an original high-energy action short film titled "Neon Alley Showdown."
The final output must be ONE combined image only, clearly divided into 2 sections:
TOP SECTION: Character design sheet
BOTTOM SECTION: 12-frame storyboard page
Create fully original anime characters. Do not imitate any existing anime, manga, game, or copyrighted character designs. Keep everything original, cinematic, dynamic, and easy to understand.
STYLE: Premium anime pre-production board, loose pencil sketches mixed with semi-rendered anime keyframes, dramatic lighting, strong contrast, speed lines, impact frames, red panel borders, blue motion arrows, handwritten notes, timing notes, and lens notes.
TOP SECTION — CHARACTER DESIGN SHEET
Use a light neutral paper-like background.
Fighter X: Young anime street brawler, around 20, shaggy bleached-blonde hair, sharp teal eyes, broad athletic build, cocky grin. Outfit: oversized hooded jacket tied at the waist, tank top, baggy cargo pants, fingerless gloves, heavy boots. Personality: loud, relentless, brute-force striker. Show front view, side view, back view, 3/4 view, charging stance, haymaker wind-up pose, grapple pose, and a few expressions.
Fighter Y: Sharp female duelist, around 21, short asymmetrical black hair with a red streak, piercing grey eyes, lean agile build, sly half-smile. Outfit: fitted leather jacket, choker, ripped jeans, tall boots, knuckle wraps. Personality: agile, evasive, counter-striker with acrobatic style. Show front view, side view, back view, 3/4 view, sidestep stance, flip-kick pose, counter-jab pose, and a few expressions.
Add small handwritten design notes and compact anime color swatches.
BOTTOM SECTION — STORYBOARD PAGE
Use a dark black background for the entire storyboard section. Do not use beige, yellow, or paper-colored background here.
Create 12 cinematic anime storyboard panels in a clean grid. Use red panel borders, blue motion arrows, handwritten camera notes, timing notes, and action notes. Keep both fighters visually consistent.
12 STORYBOARD FRAMES:

Split-screen with thick black divider: Fighter X cracking his knuckles under a flickering neon sign (upper frame); Fighter Y leaning against a wall in the rain-soaked alley, arms crossed (lower frame).

Split-screen close-ups: Fighter X's grin widens as steam rises off his shoulders; Fighter Y's eyes flick open, calm and alert.

Wide shot of both fighters facing off in a narrow neon-lit alley, rain falling, puddles reflecting light.

Fighter X charges forward with a powerful shoulder-first rush.

Tracking shot of Fighter X swinging a massive haymaker punch.

Slow-motion dodge: Fighter Y ducks and slides beneath the punch, water splashing from the puddle.

Fighter Y springs up behind Fighter X with an acrobatic flip-kick to his back.

Fighter X stumbles forward into a stack of crates, debris scattering.

Wide shot of Fighter X recovering near a dumpster, neon signs flickering above.

Fighter Y dashes in with a blur of rapid counter-jabs.

Final impact: Fighter Y lands a spinning kick that sends Fighter X crashing through a chain-link fence, sparks and debris flying from a broken neon sign.

Aftermath: rain continues falling, Fighter Y stands calm under the flickering lights, Fighter X down against the broken fence, alley and neon glow visible in background.
ENVIRONMENT: Narrow neon-lit city alley, rain-soaked pavement, reflective puddles, flickering signs, scattered crates, chain-link fences, steam vents, distant city glow.
FINAL GOAL: Make the board clean, readable, cinematic, and production-ready. The top section should clearly show the character designs. The bottom section should clearly show the 12-frame action choreography on a black storyboard background.
