Elf Capital Dimensional Cityscape

Create an epic high-fantasy science-fiction landscape titled city_concept: a luminous elven metropolis of white crystal towers across a calm turquoise lake, with snow-capped alpine mountains and soft cumulus clouds in the distance. In the lower left foreground, place one lone elven woman seen from behind, long dark hair, wearing a flowing white robe and cape with delicate gold trim, standing on a rocky flower-covered shoreline and gazing toward the city. Count the visible key elements clearly: 1 foreground elf figure, 1 central elven city, 1 large lake, 1 mountain range, 2 small white sailboats on the water, 3 sleek airships in the sky, many slender spires, waterfalls and arched bridges around the city. The left and center of the image should feel serene, organic, magical, and radiant, with leafy tree branches framing the top left and pink wildflowers in the foreground. On the entire right third of the image, add a towering dark futuristic megastructure or dimensional gate made of intricate metallic rings, cables, scaffolds, glowing blue details, and layered industrial architecture. Between the elven city and the dark machine, create a vertical shimmering iridescent energy boundary like a soap-bubble curtain, refracting the scenery with rainbow highlights and sparkling light. Use time_of_day lighting, ultra-detailed anime concept-art style, cinematic scale, ethereal atmosphere, soft bloom, crisp architectural detail, realistic water reflections, pastel blues and whites contrasted against shadowy steel. Composition: vertical 4:5 fantasy poster, viewer looking slightly downward over the lake, foreground figure at bottom left, city centered, mechanical structure dominating the right edge. Avoid text, logos, borders, modern humans, low detail, or muddy colors.
