Ultra-realistic extreme close-up macro of a single ripe dark oak acorn on a thin branch, covered in crystal-clear water droplets. Deep charcoal-black to near-navy nut with fine vertical wood grain and richly textured golden-brown scaly cupule. Vivid red seven-spot ladybug (Coccinella septempunctata) on the cupule’s top edge — glossy red elytra with precise black spots, fine black legs, delicate antennae, tiny reflective highlights. Water droplets optically perfect: sharp refraction, internal caustics, clear reflections of warm autumn light and the ladybug. Soft golden rim light kisses the edges, creating specular highlights and luminous glow through larger droplets. Behind: dried burnt-orange and deep-brown oak leaves densely covered in sparkling droplets, slightly out of focus. Creamy dreamy bokeh of soft golden-amber light orbs, clean atmospheric depth of field. Shot on 100mm macro, f/2.8, extremely high detail, photorealistic textures, natural volumetric lighting, cinematic warm autumn color grading (deep charcoal acorn, golden cupule, vivid red ladybug, burnt-orange leaves), 8k masterpiece. --ar 3:4 --v 8.1
