"A mystical and spiritual YouTube channel cover design for 'Horosun Gözü'. Central focus on an ornate eye symbol with a radiant aura, surrounded by cosmic elements like stars, galaxies, and abstract nebulae. Use a color palette of deep purples, blues, and gold accents to create a serene yet enchanting atmosphere. Include elegant, flowing text for the channel name in a sophisticated, handwritten font. The background should feature ethereal, flowing patterns or mandalas, evoking a sense of spiritual depth and cosmic wonder. The design should be balanced and harmonious, capturing both mystery and serenity."  --ar 16:9
