Luxury Brand Monogram Poster Prompt — Sculptural Letterform with Interior

Create a premium square flagship poster for a luxury interior design brand called [BRAND NAME], ultra-clean, sculptural, architectural and internationally premium, with a strong brand symbol at the center and a photoreal luxury interior revealed within it. Core composition: warm ivory-beige gallery-like background with generous negative space. At the center, place one large three-dimensional sculptural monogram form inspired by a rounded architectural letter portal — carved with smooth thickness and elegant curvature, built from the brand's initial. This monogram acts as the dominant brand symbol and also as a framing device: inside its opening, reveal a serene photoreal luxury bedroom-lounge interior at sunset, seen straight-on with precise architectural balance. The poster should read instantly as one memorable luxury design icon: sculptural letterform outside, warm interior world inside. Visual guidance: introduce one restrained curved architectural guide line above or around the monogram, echoing its geometry and gently directing attention inward. The inner room composition should reinforce this motion: terrace opening, bed alignment, rug direction, low table placement and sunset focal point all draw the gaze from the outer poster surface into the warm horizon beyond the glass. Quiet, intelligent, premium — never decorative. Restraint: keep the layout extremely minimal. Reduce all text to the essential brand hierarchy only. No secondary labels, no extra notation, no copied text, no watermark, no clutter. Preserve large breathing room around the central symbol. The final image should feel like an international flagship branding poster rather than a brochure.
