Daniela Dahf Henríquez// Flickr// Illustration - Markmaking// This illustration uses line in a similar way to how I painted one of my first hedgehogs, I think it's a good way to represent the texture of an animal by using line in this way, because it gives it that furry, or spiky look depending on how much line you use and the thickness or thinness of it. // How does the thickness or thinness of line affect the image? Does it change it?
