person taking a selfie in a mirrored room. The person is wearing a white tank top and dark pants. They are holding a phone with a black case decorated with animal images. In the reflection, there are several young individuals lying on a wooden floor, seemingly involved in a dance or exercise class. The room appears to be a dance studio or gym, judging by the mirrored wall and the activities of the people inside. A set of shelves with various items is visible in the background. The image does not contain sufficient information to confirm whether the location is the city of Votkinsk, Russia.
