Visuel de proposition skincare bleu nuit

Brand visual proposal cover and key visual (KV) for a fictional luxury beauty brand, themed around [interpreting nighttime skincare as a slow descending blue weather]. The central visual features a translucent blue essence bottle resting on a soft-mist frosted glass countertop, framed by an atmospheric nighttime window view and a delicate, semi-transparent film structure unfolding like layered weather fronts. No water splashes or human faces. Vertical proposal cover composition with the product centered, balanced with restrained graphic layering in the top-left and bottom-right, featuring ample negative space. Lighting is low-key, cold blue ambient illumination accented with ultra-fine white rim lighting on the bottle contours to highlight glass thickness, liquid refraction, and packaging edges. Color palette: [Midnight Blue #24364A, Frost Blue #9EB9CA, Bottle Cold White #E8EEF2, Deep Graphite #2F3138, a touch of Moonlight Silver #BDC6CD, very light Grey-Purple #8A8395]. Material focus: [glass refraction, soft mist acrylic, liquid suspension feel, packaging box embossing, and silver foil stamped logos]. Includes minimal, refined typography: Chinese brand name, a concise Chinese brand slogan, one English auxiliary subtitle, and a tiny functional tag in an airy, breathable layout.
