Vertical surreal fantasy composition of a large, transparent crystal hourglass floating against a deep, star-filled cosmic background. Inside the hourglass are two miniature versions of a [tropical island beach]: - Upper bulb: A vibrant daytime scene with golden sand, turquoise waves, rocky green cliffs on the left, distant blue islands on the horizon, a [bright blue sky with towering white clouds] on the right, and a single blazing sun near the upper left. - Lower bulb: The identical beach at night featuring dark blue waters, moonlit waves, shadowy islands, dramatic clouds, and a [deep starry sky with a full moon] centered above the horizon. - Connecting waist: A continuous stream of [sparkling golden sand and stardust] trickles down from the sunny beach above into the nocturnal beach below, forming a luminous glowing mound at the base. The hourglass glass is thick, glossy, and highly refractive, with crisp caustic reflections and bright edge highlights. Centered symmetrical composition, warm radiant light in the upper chamber contrasting with cool nocturnal glow below, luminous water reflections, sharp focus, rich deep blues and shimmering golds, rendered in [surreal magical cinematic realism].
