โปสเตอร์น้ำแร่มินิมอลพร้อมเส้นชั้นความสูงหักเห

A vertical high-end mineral water promotional poster in 4:5 aspect ratio with a "Contour Line Refraction Valley" composition. Subject: A label-free, minimalist transparent glass water bottle standing vertically in the lower-middle, topped with a matte foggy silver metal cap. A few subtle natural water droplets condense on the left side, with a clean crisp highlight along the right edge. Ground and Background: The bottle stands realistically on a light grey-blue mineral surface. The background consists of ultra-fine, equidistant, continuous ice-blue horizontal contour lines. Near the bottle, the lines sink downward softly as if depressed by its weight, forming a gentle canyon before returning to straight lines farther away. Optical Effect: The contour lines seen through the clear water inside the bottle undergo realistic refraction, slight magnification, and horizontal displacement, while outer lines remain unbroken and continuous without noise or crossing. Typography: Placed in the quiet negative space above the bottle is the large, narrow sans-serif title "[FLOW]" in deep navy blue with wide tracking, and beneath it a small subtitle "[MINERAL WATER]". Lighting and Style: Soft top skylight and left-rear rim lighting ensuring the glass remains luminous and transparent. Minimalist, contemporary editorial aesthetic resembling luxury drink commercial photography, without plastic CGI artifacts. Palette restricted to ice blue, misty white, deep navy blue, and subtle silver.
