This is a simple, yet eye-catching coloring page. The black hoodie is a classic shape and the white string outlining the hood adds a subtle detail. White lines running down the front of the hoodie form an interesting visual element. The pocket on the front of the hoodie gives it a distinctive look. To make the hoodie really stand out, I'd color it with a deep, rich black and use a bright color, like a blue or yellow, to outline the hood. I'd opt for a light blue for the pocket, which will provide a nice contrast with the black. For the white lines, I'd use a light gray to make it stand out against the black hoodie. This will make the piece truly unique and bring out all the shades used in the coloring page.
