Last night students made drawings of textural objects (i.e. bark, leaves, pine cones, feathers, etc.) Alex's drawing above is rich with value and mark-making. Swirling and flowing marks capture the fluidity of the wood grain. Texture drawings are essentially value drawings so contrast is key to capturing the subtle variations of color and volume. Furthermore, the success of Alex's drawing is due in part to his use of additive as well as reductive drawing techniques. Notice how the light areas "pop" through the marks and darker tonalities.
