This quaint scene depicts a deep valley running through the center of a wide pipe. The walls are smooth and even, while the floor is jagged and strewn with pieces missing from the edges. A silver hue is suggested by the initial outlines but can be further enhanced for a more metallic shimmer. Why not experiment with light accents of color on the walls, or a darker hue in the shadows of the valley to create a sense of depth? A few wisps of color in floating across the valley add interest and intrigue, while splashes of brighter colors on the pipe’s exterior creates a subtle frame around the valley. It's a fun opportunity to explore creative color combinations, so let your imagination be your guide!
