Realistic fantasy portrait of a dryad, a spirit of the forest. Her body is covered with natural bark patterns that look like a second skin — smooth, flexible, and seamlessly grown from her form. Subtle lines of moss and veins of green light run beneath the surface, giving her a living, organic appearance. Her eyes reflect forest light, and her hair flows like fine roots mixed with leaves. The background shows a softly lit woodland filled with warm golden rays. SFW, fine art concept art, cinematic realism, detailed textures, serene expression, nature spirit theme., harpy,
