Goal: Create a dark anime cyberpunk character design sheet for {argument name="character name" default="a futuristic female vocalist"}, centered on a striking idol/singer with glowing electric-blue music effects, rendered as high-detail concept art on a black background.
Canvas: Wide horizontal 16:9 character sheet, black paper texture background, thin gray divider lines separating studies, white handwritten annotation labels, high contrast lighting, cyan-blue glow accents.
Main subject: A young anime-style female vocalist with {argument name="hair color" default="black hair with vivid cyan-blue streaks"}, long messy high ponytail, wet/shaggy layered bangs, pale skin, sharp blue eyes, and a cool intense expression. She wears a transparent visor headset over one eye, a glowing blue star hairpin, over-ear tech headphones, black fingerless gloves, a black choker, a white cropped top, an oversized glossy black-and-white streetwear jacket with straps and zipper hardware, loose black cargo pants, belt chains, and chunky sneakers. She holds a futuristic microphone near her mouth, with bright cyan soundwave ribbons and angular waveform shapes spiraling around her body.
Layout: Place one large central full-color hero illustration occupying the middle-left and center, showing the singer from thighs up, facing slightly left, singing into the glowing microphone. Surround her with exactly 3 labeled study sections:
1. Turnaround & Faces: In the upper-left, include exactly 3 mini turnaround full-body poses labeled as front view, back view, and side view. Beneath them include exactly 3 white silhouette studies matching the same front, back, and side profile. Along the bottom-left, include exactly 4 expression portrait panels: neutral serious face, singing with mouth open, downward cool gaze, and close-up singing into the microphone.
2. Pose Study: In the upper-right, include exactly 4 dynamic full-body/action pose drawings: “UNLEASH” with the singer blasting a jagged blue waveform from the microphone, “LEAP” with her airborne and twisting while performing, “LOW SHOT” crouched and pointing the glowing microphone forward, and “COOL DOWN” standing relaxed with hands in pockets and jacket hanging loose.
3. Detail Study: Along the lower-right, include exactly 5 close-up detail panels labeled: “VISOR HEADSET & FACE,” “GLOWING STAR HAIRPIN,” “JACKET TRIM & HARDWARE,” “GLOVE & SILVER RINGS,” and “GLOWING MIC & WAVEFORM.”
Visual style: Gritty semi-realistic anime concept art, painterly brush texture, crisp ink-like highlights, dramatic rim lighting, glossy black fabrics, luminous cyan electric effects, sketchbook production-sheet presentation, hand-drawn white lettering. Use the accent color {argument name="glow color" default="electric cyan blue"} throughout the soundwaves, headset lights, hair streaks, microphone grille, and star hairpin.
Text content: Use handwritten white English labels exactly as visible: “1. TURNAROUND & FACES,” “MINI TURNAROUND,” “SILHOUETTE STUDY,” “EXPRESSION STUDY,” “2. POSE STUDY,” “UNLEASH,” “LEAP,” “LOW SHOT,” “COOL DOWN,” “3. DETAIL STUDY,” “VISOR HEADSET & FACE,” “GLOWING STAR HAIRPIN,” “JACKET TRIM & HARDWARE,” “GLOVE & SILVER RINGS,” and “GLOWING MIC & WAVEFORM.”
Constraints: Keep the background black, avoid a clean white model-sheet look, do not add extra characters, logos, watermarks, or unrelated props. Maintain exactly 3 mini turnaround poses, 3 silhouettes, 4 expression portraits, 4 pose-study drawings, and 5 detail panels.
