These drawings by Lui Ferreyra are simple yet beautiful with how she uses color to show shadows and shades. Lighter colors we uses for areas that had light being placed on them. While darker hues of colors where use for areas that had shadows. As well as all the shading lines ares going in the same general direction to help with the movement of the piece and to help with general look of it. Also she used geometric shapes for her colors for when she switch from one to another.
