企业风格简约黑白9:16竖版海报设计

9:16 vertical poster, high-contrast black & white (chiaroscuro), subtle film grain. Use my uploaded portrait as the sole identity reference—100% faithful reproduction of the same face (bone structure, eye spacing, nose bridge, lip shape, jawline must be consistent). No beautification, no face alteration, no drift. High-end refined portrait skin texture at commercial retouching quality. Composition: Vertical split down the middle. Left half is a close-up realistic photo of the face (from forehead to chin, face nearly fills the frame), slightly turned but almost frontal; hard side lighting from the left side of frame, deep shadows, clear tonal layers. Right half is pure white background, but uses ultra-bold black serif typeface in vertical stacked layout (large text, full-bleed, tight, no border margins) as a "knockout mask": the text itself is filled with the texture of the same portrait's right half of the face, so the face appears to continue through the letterforms onto the right side; area outside the text remains pure white. Requires precise alignment: nose bridge, lips, jawline should still read as a continuation of the face within the letter shapes. Text rules: Randomly generate one English motivational phrase (ALL CAPS, 3–8 short words, rhythm like a poster tagline). Optionally add a smaller English subtitle at the bottom. English only throughout. • Tone: restrained, sharp, brief (e.g., "KEEP GOING", "DO THE WORK", "STAY SHARP", "NEVER SETTLE", "OWN YOUR PATH"—similar length and punch, but not limited to these examples)
