Prompt
A three-quarter view of a single transparent glass brain resting on a pale plinth under soft backlighting. The glass is perfectly clear, its outer surface smooth, polished and unbroken, with the brain's folds and fissures modelled in the solid glass.
Entirely inside the glass volume a storm is suspended: one dark grey cloud sits low between the inner folds, fine branching lightning arcs from it through the clear space, and tiny raindrops hang caught mid-fall in the hollows of the glass. The cloud, the lightning and the raindrops all sit within the brain's outer surface, plainly contained by the smooth glass rather than floating above or around it.
Soft backlighting glows through the glass from behind, lighting the storm from within and outlining the brain's silhouette against a quiet dark backdrop, with the plinth's gentle reflection beneath. The frame is a 16:9 wide composition holding the glass brain and its internal storm with clear margin on every side, and the scene stays unlettered with no text anywhere.
