Ethereal Twilight Horizon

abstract atmospheric horizon gradient, soft blurred bands of color like a dreamy twilight sky, deep navy blue upper sky fading into violet and lavender, broad diagonal sweep of pink and magenta mist across the center, pale icy blue glow near the lower left horizon, warm golden yellow strip along the bottom edge, smooth velvety texture, subtle cloudlike streaks, minimal composition, no distinct objects, ethereal ambient color field, long exposure softness, serene cinematic sky abstraction
