Architectural Fantasy of the Resonant Instrument Cathedral

Full prompt

A surreal architectural fantasy painting executed in a 9:16 portrait aspect ratio, depicting a colossal Gothic cathedral organically constructed from classical string instruments. Towering nave pillars take the form of massive carved cello scrolls and ebony fingerboards, rising vertically to support ribbed vaulted ceilings fashioned from interlocking spruce soundboards with glowing f-holes radiating golden light. Taut cello and violin strings stretch hundreds of feet from the stone floor to the soaring arches like illuminated architectural cables, vibrating with delicate harmonic energy. The dramatic vertical perspective pulls the viewer's gaze upward through rich mahogany columns toward midnight-indigo vaults, rendered with meticulous oil-glaze realism and luminous atmospheric depth tailored for an immersive full-screen vertical story.
