Huldra. The forest watcher.

sumi-e style, a female creature known as a Skogsrå stands in a forest during the evening, her black eyes looking at the viewer with a mysterious expression. She has green, long hair that cascades over her shoulders, pointy ears, and small horns on her head, with a cow tail swaying gently behind her. She wears a white dress and skirt, and stands barefoot on the lush grass. The background features tall trees and a soft evening glow, creating a serene fantasy atmosphere.
