3D渲染中式美丽侨乡科创宣传艺术字

A realistic 3D rendering of the Chinese text "美丽侨乡 科创新城" (Beautiful Hometown of Overseas Chinese, Tech Innovation City), created as a layered metal sign. The bottom layer is a thick, flat plate made of textured, dark blue painted iron, with visible subtle brush strokes and slight metallic sheen. On top of this blue base, the individual white Chinese characters are prominently stacked as a separate, solid iron layer with a thickness of about 3 cm. The white characters have a rough, cast iron texture with tiny rust spots and a slightly weathered look, contrasting sharply against the smooth dark blue background. The letters cast a soft shadow onto the blue base. The overall scene is well-lit with dramatic studio lighting from a low angle, emphasizing the depth, layers, and gritty metallic material. Highly detailed, 8k resolution, photorealistic, depth of field.
