Prompt
[organic tunnel of filaments] fills the frame vertically in a 2:3 ratio, occupying the central and center-right area and leaving narrow negative bands at the left and top edges for breathing space. The subject is medium-large relative to the crop, with the circular cavity sitting slightly right-of-center and the swirling strands cascading toward the lower third of the frame. Lighting is dramatic and directional, with soft rim illumination from [deep teal-blue shadows] and contrasting warm reflections from [pulsing orange highlights] that catch edges and small surface beads. Surface texture reads as fine, wire-like strands with discrete glowing nodes and smooth reflective bands that show subtle specular streaks along curves. Background is shallow and heavily defocused with layered bokeh discs concentrated in the upper-left quadrant so the cavity remains the focal center. Produce the image as hyper-realistic digital-painting style with crisp midtown detail, soft outer blur, and natural falloff suited for vertical wallpaper.
