Photorealistic minimal still life of a vintage clear glass hourglass standing upright on a white marble surface, with pale gray veining continuing into the softly blurred marble backdrop. The upper bulb is nearly empty and transparent, while vivid lime green sand rests in a smooth sloped layer in the lower bulb, suggesting time running out and an approaching deadline. Clean high-key natural window light from the upper left creates soft reflections on the glass, a faint shadow at the base, and a calm, contemplative mood. Cool white, soft gray, and fresh green color palette. Vertical composition with the hourglass slightly below center and generous negative space above, shot on an 85mm lens, f/3.5, shallow depth of field, crisp glass edges, realistic refraction.
