优雅覆盆子甜点海报

Create a premium vertical dessert campaign poster for a fictional haute patisserie brand called ROSÉVA, combining Transit-style restraint with Orbit-style airy motion. The image must feel ultra-clean, elegant, soft, editorial, and commercially luxurious, while keeping the mini cake as the absolute visual hero. No copied text, no watermark, no clutter. Main composition: A single signature raspberry mini cake floats at the center-lower portion of the frame against a seamless dusty-rose studio background. The cake has a clean cylindrical mousse body, a thin golden biscuit base, faint raspberry compote seams near the lower edge, and a delicate pale-pink berry glaze gently dripping with realistic gravity. On top sits a sculptural swirl of whipped vanilla cream, crowned with several fresh raspberries and a few deep berry accents arranged in a refined clustered composition. Around the cake, place only a minimal orbit of oversized raspberries at different depths, with two or three softly blurred foreground/background berries and one or two sharper mid-depth berries, creating a graceful circular flow around the hero product without crowding it. Transit restraint: Keep the layout highly disciplined and premium. Preserve large negative space in the upper half for typography. Reduce all secondary fruit and decorative elements to the minimum necessary. The composition should read instantly: headline, hero cake, soft berry orbit, brand mark. No extra props, no crumbs scatter, no busy garnish. Orbit motion: The surrounding raspberries should feel like they are gently revolving around the cake in a soft suspended arc, creating elegant movement and flavor aura. Their placement must guide the eye in a subtle circular path toward the whipped topping and back down to the mousse body. Motion should feel light, poetic, and controlled, never chaotic. Typography and branding: At the upper center, place an elegant English script headline: "Softness in Bloom". Beneath it, add a refined uppercase serif line: "RASPBERRY PETIT GATEAU". Add a faint oversized translucent background word layer as a subtle graphic accent, softly integrated and partially cropped. At the lower center, place a very small luxury ROSÉVA logo mark. Typography must feel editorial, feminine, premium, and internationally commercial. Lighting: Soft diffused studio lighting from the upper front-left, with gentle right-side fill and a subtle overhead highlight on the whipped cream and raspberry surfaces. Shadows should be short, soft, and low-contrast, lightly anchoring the cake while preserving an airy bright atmosphere. Increase sculptural separation slightly so the mousse body, frosting ridges, and berry forms feel dimensional and premium. Material rendering: The mousse body must appear chilled, creamy, and ultra-realistic, with fine aerated microtexture and subtle natural porosity. The whipped topping should feel dense, smooth, and freshly piped, with refined ridges and a soft semi-matte sheen. Raspberries must show realistic drupelet structure, velvety bloom, seed detail, delicate translucency, and fresh natural irregularity. The pink glaze should appear lightly viscous, glossy, and physically believable. The biscuit base should show crisp fine crumb structure and warm toasted color. Color system: Dusty rose pink, whipped-cream ivory, raspberry crimson, pale blush, soft biscuit beige, and a few deep berry-red accents. The palette must stay restrained, elegant, and softly appetizing, with the red fruit acting as the controlled focal contrast. Style: Luxury patisserie advertising, minimalist editorial food photography, flagship dessert poster, Cannes-level commercial food image, ultra-realistic, feminine, tactile, premium, and globally marketable. Image quality and physical constraints: Ultra-detailed, high-resolution, crisp frosting edges, realistic berry skin texture, correct shallow depth-of-field falloff, clean background, believable floating physics, natural glaze gravity, no distorted cake geometry, no plastic food look, no dirty shadows, no dead-black areas, no random clutter. Negative prompt: cheap bakery flyer, copied original slogan, copied original brand text, cartoon dessert, plastic mousse, fake CGI frosting, oversaturated pink, messy composition, too many raspberries, cluttered background, distorted cake shape, broken floating physics, melting structure, artificial berry texture, harsh shadows, flat lighting, unreadable typography, watermark, random labels, low-end packaging style
