Luxury Durian Brand Key Visual

A {argument name="ratio" default="3:4"} vertical brand key visual for a new product launch poster, designed as the main visual for new product communication. The subject is a {argument name="subject" default="durian gift box"} in the fresh fruit category, with an overall tone of strong tropical luxury. The composition uses a vertical centered focus, with the subject enlarged in the middle and a restrained sense of space surrounding it. The background is a high-end tropical fruit gift setting, incorporating soft-material platforms to establish spatial layers for the brand. The focus is on the spiked shell structure and the dense texture of the fruit pulp, using dramatic unidirectional spotlights and controlled reflections to establish the subject's silhouette, material reflection, and brand mood. The color system uses {argument name="color scheme" default="Golden Durian Yellow #C9A347 + Milk White #F4EEDF + Dark Brown-Green #5B5847"}. The typography system includes title + subtitle + logo area, with the text safety zone placed at the top title area to ensure clear margins for the title, slogan, and logo. The overall result should be a genuine, deployable brand key visual, rather than a typical e-commerce main image or detail page collage, avoiding excessive parameter stickers.
