GPT Image 2 City Artistic Poster Prompt

A calligraphy brush in the act of painting traces an S-shaped calligraphic stroke running from the bottom right to the top left; within the brushstroke are miniature landmark views of {argument name="city name" default="Guangzhou"}, the whole rendered in a 3D, highly saturated poster style. The content within the brushstroke consists of {argument name="city name" default="Guangzhou"}'s iconic, representative buildings, blending the local traditional architectural style with local modern architecture to form a visual layering where old and new merge. If the city has a body of water (such as a river or bay), incorporate the corresponding water feature into the brushstroke, creating a hazy, mist-shrouded atmosphere over vast waters to enhance the sense of spatial depth. Overall, the brushstroke shows a natural ink-diffusion and broken-edge effect, while still keeping the city's structure clear and rich in detail. The tip of the brush sits at the end of the stroke in the upper-left corner, forming a dynamic moment of "currently being painted." Outside the brushstroke is a large area of pure, blank background, emphasizing an Eastern minimalist composition. At the start of the brushstroke, add the text: {argument name="city name" default="Guangzhou"} and a line reading {argument name="city slogan" default="a short slogan for the city"}, with the text arranged naturally along the direction of the stroke. Overall style: a fusion of traditional Chinese style and modern three-dimensional art, highly detailed, highly saturated yet clean, vivid colors, realistic physical lighting and shadow, HDR, 8K resolution, commercial-grade visual quality.
