Cosmic Impasto Oil Painting of a Swirling Celestial Spiral Vortex

Full prompt

Expressive fine art impasto oil painting depicting a swirling celestial spiral vortex, reimagined in a wide 16:9 horizontal format for a website hero image. Sculptural palette knife strokes sculpt the galactic nucleus in thick, tactile layers of zinc white, Naples yellow, and cadmium gold slightly left of center, radiating rotational light across the wide linen canvas. Sweeping spiral arms curl outward horizontally in rich sweeps of Prussian blue, cobalt violet, and cerulean, dotted with raised impasto flecks of pure white and magenta depicting nascent star clusters. Deep umber and lamp black glazes carve textured dust lanes through the paint layers. The right side of the wide canvas offers calm, breathing negative space washed with dark indigo glazes, accentuating directional drag marks, canvas tooth, and dynamic rotational motion.
