PROMPT:
Create an abstract expressionist masterpiece depicting a mesmerizing vortex of swirling iridescent tendrils, reminiscent of celestial bodies colliding in mid-air, set against a background of deep, rich blues and purples. Incorporate vibrant hues of emerald green, sapphire, and amber, with subtle hints of silver and gold, but limit the use of pink to near absence. Achieve a photorealistic effect by blending bold, textured brushstrokes with delicate, wispy details. The overall composition should evoke a sense of dynamic energy and cosmic wonder.
