Portrait éthéré à l’aquarelle d’une fille fantastique sereine aux cheveux menthe

An ethereal watercolor portrait of a young androgynous fantasy character with mint-green hair in a loose ponytail, pale skin, and a serene, closed-eye expression. They wear a white high-collared shirt with delicate light-blue gem buttons and a pale-blue pendant, accented by a soft shawl or cape with subtle blue tones. A small blue facial mark near the cheek adds mystique. The background is a dreamy pastel wash of pinks, purples, peaches, and sky blue with watercolor splashes. Soft, diffused lighting, painterly textures, fine linework, and a gentle, romantic atmosphere. 3/4 view head-and-shoulders with softly rendered hair strands and a hint of gold trim on the clothing.
