She retains her long dark-brown hair and striking deep green eyes, now complemented by subtle avian features: feathered markings around her shoulders, sharp talon-like fingernails, slightly pointed ears, and enormous dark feathers emerging from her back to form partially spread wings. Her figure is that of a supermodel, with large natural breasts, toned arms and abs, and divinely shaped hips. Her eyes have a faint predatory gleam. She wears an elegant dark forest-green fantasy gown with a fitted bodice, layered flowing skirt, feathered accents, delicate black lace, and antique silver jewelry. The costume incorporates feathers naturally into the design without becoming a literal bird costume. She stands on a ruined stone overlook above a misty forest valley, leaning slightly toward the camera with one wing extending behind her. Her expression is confident and faintly predatory, with a knowing smile suggesting she has spotted something interesting below. Wind moves her hair, feathers, and dress dramatically. Behind her are jagged cliffs, ancient stone ruins, twisted trees, and distant fog rolling through the valley. Moonlight creates a silver rim around her wings and hair.
