Affiche de salutation matinale avec traînées de mouvement urbain

Build a morning-greeting visual around any theme: first translate the theme's semantics into a core vehicle with a forward direction, placed in the lower-middle right of the frame, keeping a clear large silhouette with few key details, while slow-shutter panning creates strong horizontal motion trails, edge doubling, and a sense of air being swept; the motion runs from lower-left to upper-right, with the lit side forming a soft glowing rim and localized warm halos, so the emotion of "moving toward the light" is perceived before the concrete subject. Keep the upper area open, clean, and continuously high-key as breathing room for large type; the lower area carries weight with a low-camera environment, dark foreground, and slightly blurred texture, distant contours softened, the core vehicle partially merging with the background within the speed blur, yet the visual focus staying in the bright right-of-center area. Colors derive from the theme: pick a high-brightness, low-to-mid saturation primary that best expresses morning, hope, and cleanliness covering large background fields, paired with a low-brightness dark tone of the same theme concentrated in the lower environment, near-white carrying the lit surfaces and main text, plus a tiny amount of high-saturation accent drawn from complementary or adjacent warm hues; overall bright, transparent, airy, with pure color fields, warm light seeping in only along the motion direction and never forming muddy composite colors. Typography uses layered editorial design: at the top, an oversized white English handwritten script spans the empty space, thin connected strokes, exaggerated ascenders/descenders, and long tail flourishes creating light speed; beneath it, two lines of large high-contrast Chinese serif type with generous letter spacing and offset line breaks, interspersed with a small italic year or short annotations; at the top left and right, small circular marks, short brand lettering, the date and weekday form a quiet corner order. On the left, a hairline vertical rule and rotated small serif English lengthen the reading path; the dark lower zone concentrates short copy, opening with a warm-toned script line as an emotional prelude, then a bold white sans-serif headline and thinner white body text forming a clear hierarchy, closed by a small square info stamp at the bottom right. All text content is generated from the current theme, preserving ample breathing space, a light-top heavy-bottom structure, and the tension of the dynamic right-side focus; the imaging keeps real-photography natural backlight, lens flare, shallow depth of field, and panning trails, staying clean and soft, never treating the speed blur as a uniform filter, and never letting text crush the subject's silhouette or the morning-light corridor.
