A room with children in blue martial arts uniforms lying on a yellow and black checkered mat is observed through a window. A patterned red rug with white fringes is resting on a wooden surface in front of the window. Several children are lying on their stomachs on the mat. An adult in black clothing is attending to one of the children in the background. A child with a white belt is kneeling next to another child on the mat. Some of the children are wearing socks. The window frame is dark. Tiles can be seen below the window.
