Enseigne lumineuse carrée en saillie sur bâtiment en béton - Art IA | PicLumen

A realistic architectural photography, close-up eye-level shot of a square double-sided projecting light box sign mounted on a light grey concrete building exterior. The sign has a thick black metal frame and a vibrant lime green background. The graphic on the sign is a dark grey minimalist geometric logo depicting a stylized plant or tree: two symmetrical upward-facing leaf shapes above a horizontal base with three semi-circular cutouts resembling roots. The sign is attached to the wall via a black metal bracket. In the background, there is a recessed window with black frames below, reflecting the blue sky and nearby buildings. Bright natural sunlight, clear daytime, casting strong sharp shadows to the left, highlighting the 3D depth and thickness of the box. Sharp focus, high contrast, urban setting, slightly low angle perspective, concrete texture, 8k, photorealistic.
