Left Sofa: (Rendered as Designer's sofa): Outlined sofa lightly with a red or #B pencil, then render each surface of cushions by applying Chartpak Colorless Blender first and use the value sequence of Sunset Pink, Salmon, Deep Salmon, Scarlet and Maroon to achieve a nice Graduate Value Change to White Space. Lastly, height-ed it with Chartpak Maize and Prismacolor pencil True Blue. Sharpie was used to show shadows and Grey #1 and #2 for the floor. A plant is added to create Contrast Line against the white cushion.
Right Sofa: (Rendered as Artist's sofa): Outlined sofa lightly with a red or #B pencil, then render the entire sofa with Chartpak marker Maroon. The values and brightness of light are achieved by applying Prismacolor pencil White. Shade sides of sofa were obtained by adding color Maroon a couple of times to show more depth. Sharpie was used to show shadows. Use Chartpak Sunset Pink and Grey #1 and #2 for the floor. Add plant with Light Color to add Color Glow and create interest.
Graphic principles were shown in bold and colored.
