Prompt

Original breathtaking prismatic architectural fantasy artwork. A circular ivory observatory with ONE immense luminous opal telescope dome sits on a narrow island of dark basalt in a perfectly still turquoise alpine lake. The dome is translucent rainbow glass with clean precise ribs, opening toward a huge pale crescent moon over snowy mountain peaks. A slim elegant footbridge leads from the near shore to the single building. Dusk gradient from violet to apricot, perfectly legible reflection, restrained gold accents, fine mineral textures, enormous sense of silence and wonder. Low centered architectural view, clear focal hierarchy, no people, no extra domes.
