Vertical Glissando Waterfall of Prismatic Harp Ribbons

Full prompt

A 9:16 portrait photograph presenting a luminous cascade of prismatic harp ribbons inspired by a musical glissando, composed for a phone lockscreen. Slender nylon and copper strings descend from a warm polished walnut harp arch nestled in the lower half of the frame, unraveling into undulating streams of iridescent light that bend into spectrum reflections of cyan, magenta, and warm gold. The light ribbons pool rhythmically onto a wet slate floor below, sending bouncing droplets across reflective raytraced caustics. Studio rim lighting outlines each translucent ribbon against deep slate-gray shadows, while the upper forty percent of the composition remains calm, dark, and uncluttered, providing pristine negative space for clock widgets.
