Group dance on a waterside wooden platform in Moscow

A group of people are dancing outdoors on a wooden platform next to a body of water. The people are of various ages and genders, dressed in casual clothing. They appear to be following instructions from a leader, possibly a dance instructor, who is not fully visible in the frame. In the background, a boat is moving across the water, and a bridge and buildings are visible along the waterfront. The sky is blue with some clouds, indicating it is daytime. The overall scene suggests a public gathering or event.
