Generate a NEW original Vietnamese historical YouTube thumbnail poster for the project title: "NGÔ QUYỀN — TIẾNG SÓNG BẠCH ĐẰNG MỞ LẠI NON SÔNG".

16:9 horizontal composition, true cinematic documentary poster, highly clickable but historically grounded. Central subject: Ngô Quyền, early 10th-century Vietnamese hero and commander, Vietnamese facial identity, strong healthy build, stern calm eyes, resolute expression, standing at the decisive moment before the Battle of Bạch Đằng. Use the attached Ngô Quyền reference image for IDENTITY ONLY: preserve age range, face structure, hair, expression tendency, and costume language consistency. Do NOT recreate the reference sheet or any character-sheet layout.

Scene concept: one single cinematic story scene on the tidal Bạch Đằng River at dawn or storm-lit dusk. Ngô Quyền stands in the foreground on a wooden war boat or muddy riverbank, commanding the trap. Behind him: rows of sharpened wooden stakes emerging beneath tidal water, Vietnamese fighters preparing in tense silence, reeds bending in the wind, war boats, cold mist, dark clouds splitting with bronze light, distant enemy fleet hinted in the background. The image must communicate strategy, destiny, and the turning point that reopened Vietnamese independence.

Visual style: Vietnamese historical ink-wash poster, antique parchment texture, sepia/bronze/charcoal palette with restrained deep crimson accents, hand-painted feel, dramatic light, layered mist, elegant brush textures, premium documentary thumbnail energy.

Text in image: include ONLY the Vietnamese title text "NGÔ QUYỀN" in large expressive brush calligraphy, placed on the LEFT side in a balanced dark ink title area with strong readability and generous negative space. Optional much smaller secondary line: "BẠCH ĐẰNG 938". No other text.

Composition priorities:
- One cinematic narrative scene, not a lineup, not a reference sheet, not multiple views.
- Ngô Quyền should dominate the composition but leave breathing room for title readability.
- Make the stakes and tidal-river trap visually legible.
- Use dynamic contrast and silhouette clarity suitable for YouTube thumbnail viewing at small size.
- Historically grounded early medieval northern Vietnam, not later dynasties.

Hard negatives: no character sheet, no turnaround sheet, no concept art board, no multiple views, no front/back pose sheet, no lineup, no floating costume pieces, no isolated armor pieces, no design sheet, no modern objects, no photorealism, no 3D render, no anime, no European armor, no Chinese imperial throne scene, no overcrowded text, no watermark, no logo.
