Miniature bioluminescent city rises from mossy windowsill

A miniature city of towering skyscrapers, resembling giant, luminous mushrooms, springs from a patch of moss on a forgotten windowsill. Tiny, winding paths connect these glowing structures, illuminated by a profusion of bioluminescent spores, casting a mysterious yet enchanting light. The scale is dramatically reversed: the fantastical cityscape makes everyday objects like dust motes and individual hairs appear minuscule. The artwork is rendered in a surreal, low-poly 3D style, similar to the atmospheric concept art of Simon Stålenhag and the richly detailed world-building of Sparth, with dramatic chiaroscuro and a deep palette of emerald green and sapphire blue. UHD, photorealistic.
