Ribbons interwoven with a common thread

The exercise of entwined ribbons already experienced in a previous lesson, it is made more complicated! I’ve found this idea on one of my favorite Art Blog of ever Mini Matisse created by my friend Nic Hahn. A colorful ribbon connects multiple drawings in a tangle of white ribbons. The exercise allows experimenting the light and shade and the effect of depth: with shadows put to the right place the image appears three-dimensional, and the black background contributes to the effect.
