GPT Image 2 Invitation à la création d'une affiche artistique pour la ville

A writing brush in the process of painting, tracing an S-shaped calligraphy stroke from the bottom right to the top left. Within the stroke is a microscopic landscape of landmarks from {argument name="city name" default="Guangzhou"}, styled as a 3D high-saturation poster. The content within the stroke features iconic buildings of {argument name="city name" default="Guangzhou"}, blending local traditional architecture with modern structures to create a visual layer of old and new. If the city has a water system (such as a river or bay), incorporate the corresponding water body into the stroke to create a misty and atmospheric feel, enhancing the sense of spatial depth. The stroke as a whole shows natural ink diffusion and edge fragmentation effects while maintaining clear urban structures and rich details. The tip of the brush is at the end of the stroke in the upper left corner, capturing a dynamic moment of "currently drawing." Outside the stroke is a large area of clean white space, highlighting an Oriental minimalist composition. Add text at the beginning of the stroke: {argument name="city name" default="Guangzhou"} and a {argument name="city slogan" default="short slogan for the city"}, with the text naturally arranged along the direction of the stroke. Overall style: A blend of traditional Chinese style and modern 3D art, high detail, high saturation but clean, vibrant colors, realistic physical lighting, HDR, 8K resolution, commercial-grade visual quality.
