An ethereal Amazonian water spirit with long flowing midnight black hair billowing like seaweed underwater, emerging from a crystal-clear bioluminescent lagoon at twilight, luminous amber eyes with detailed white light reflections, wearing an elegant costume of woven rainbow macramé and floating water lilies, cel-shaded with bold black outlines, dramatic upward composition from below looking through turquoise water, rich deep teal and warm golden amber palette with glowing bioluminescent particles, mystical contemplative mood, floating luminous fish and glowing flower petals, South American mythology spirit concept art with soft bokeh of distant rainforest canopy
