The video begins with a close-up of a hand holding a black marker, which is used to color in a sketch of a gecko. The gecko has a textured body, with scales and a prominent eye that is colored in blue. The artist uses the marker to fill in the details of the gecko's body, including its limbs and tail. The video progresses to show the gecko in various stages of completion, with the artist adding depth and shading to the drawing. The final frame of the video shows the completed drawing of the gecko, with a shadow cast beneath it, giving it a three-dimensional appearance.
