Starting Position of Mountain Pose (Tadasana) in Prenatal Yoga

Starting Position of Mountain Pose (Tadasana) in Prenatal Yoga: I need an image that illustrates the first step of Mountain Pose (Tadasana) in prenatal yoga. The image should show an experienced, pregnant yogi standing in a quiet environment at home. The yogi should explain the posture in the image, but she should not look directly at the camera as if she were posing. The style should be relaxing and professional, with soft colors and a minimalist background. The yogi should be standing, clearly showing the activation of the leg muscles. She should raise her kneecaps without locking her knees, with her legs active but without excessive tension. The yogi must have a concentrated and serene expression, focused on the posture she is performing.
