The video shows a person drawing a sailboat on a piece of paper. The person starts by drawing the outline of the sailboat and then proceeds to add details such as the sails and the hull. The person uses a pencil to sketch the sailboat and then uses a pen to add shading and depth to the drawing. The person also draws the water around the sailboat, creating the illusion of the sailboat sailing on the water. The drawing is quite detailed and realistic, with the person taking care to add the right amount of shading to make the sailboat and the water look three-dimensional.
