A 9:16 vertical brand Key Visual (KV) directly usable for mobile full-screen splash ads. The theme centers on theme, with the main product being product. The overall brand language is urban sophisticated, using a full-screen vertical immersive composition. The subject is oriented to the left, with a large horizontal text white space on the right. The background is a low-illumination cosmetics studio space, incorporating low-density floating particles to establish brand spatial hierarchy. Focus on representing the brush structure and tube body highlights using cold white futuristic volumetric light, allowing the subject's outline, material reflection, and brand mood to exist simultaneously. The color system uses color scheme. The text system includes title + slogan + date/series information, with the copy safety zone placed in the low-density information area at the bottom to ensure clear white space for the title, slogan, and logo. The overall look should be a genuine deliverable brand KV, not an e-commerce main image, not a detail page collage, and not filled with parameter patches.
