Pink cosmos flowers with dark foliage on black background.

Digital botanical illustration employs precision rendering of four pink cosmos flowers at various bloom stages against pure black background. Technical execution demonstrates fine detail in petal striations, dark burgundy stamen structures, and gradient transitions from pale salmon to coral pink hues. Foliage rendered in dark teal-blue tones with visible veining. Composition arranged vertically with blooms at different depths, showing both opened flowers and closed buds. High contrast lighting creates dimensional separation.
