Infinite Stretching Echo

Mirror selfie in a stretching studio. A girl sits on a light-colored Pilates mat on a light wooden floor. Clothing: cropped graphite hoodie and graphite loose high-waisted sweatpants, light sneakers. Hair is gathered in a high ponytail, black AirPods Max on the head. Pose: body slightly turned towards the mirror, both legs bent and positioned to the side, one knee on the floor, the other looking straight up, one hand stretched forward holding the phone in front of the face, the other hand resting loosely on the waist. Background: a long studio with a full mirror wall, creating an infinite mirror perspective of the hall. Ceiling with continuous cold LED lighting around the perimeter. To the left is a row of floor-to-ceiling windows with black frames. The walls are light, the hall is almost empty. Lighting is soft warm from above plus cold ceiling lighting.
