A woman, her energy palpable as she straddles a a large pillow with a look of intense determination in her eyes. She is clad in bike shorts that cling to her legs, which are bent and firmly planted on either side of pillow, as if she's riding the pillow. She is bouncing up and down on the pillow. The pillow lies beneath her, the woman's mouth is wide open in an involuntary yawn, her tongue out. Her eyes intensely focus on the camera. The woman is in full view in the shot, her pigtails bounce with each rhythmic movement she makes, emphasizing the innocent yet curious nature of the encounter. Her cheeks are flushed, and her eyebrows slightly furrowed, as if she's both concentrating on her task.
