Ethereal cross-processed vintage film photograph, evoking a sense of mystique, featuring a high-quality pro photo of a stunning red ruby crystal woman creature, seated regally on a gnarled tree branch, surrounded by the ominous yet enchanting darkness of a summer forest at dusk. Her crystalline skin glimmers with a deep, rich red hue, as if infused with the essence of rubies. Her features are delicate, with high cheekbones, a slender nose, and full lips that curve into a subtle, enigmatic smile. Her long, flowing hair cascades down her back like a fiery waterfall, with hints of orange and amber tones that complement her crystal complexion. The 135mm portrait lens captures the intimacy and mystique of the scene, with the forest's dark, muted greens and browns providing a striking contrast to the creature's radiant, gemstone-like presence.
