Create a highly detailed and super realistic image of a mid-forty-year-old woman performing the downward facing dog yoga pose. The setting is a serene yoga studio with soft, natural lighting streaming through large windows. The woman has medium-length brown hair tied back in a loose ponytail. She wears a fitted, light blue yoga top and dark gray leggings. Her expression is one of focused relaxation, eyes softly closed, with a slight perspiration visible, indicating physical effort. The background should include minimalistic yoga accessories like a rolled towel, a small plant, and a calm, muted color palette to enhance the tranquility of the scene.
