An extreme close-up, hyperrealistic photograph captures a single raindrop clinging to the iridescent wing of a robotic butterfly. Within the raindrop, a miniature cityscape of towering crystal skyscrapers is reflected, warped and distorted by the water's surface tension. The background is a soft, bokeh blur of neon lights. The butterfly's metallic wing is intricately detailed with glowing circuits and tiny rivets. The entire scene is bathed in the cool, blue light of a cyberpunk metropolis, creating a sense of melancholic beauty and technological wonder, 4k resolution, a true masterpiece of detail and composition.
