On 18 x24 in., hand-toned, drawing paper using charcoal materials and erasers make a drawing of the space under your sink; any sink. Use value subjectively to emphasize and exaggerate the lighting conditions and the character of the space. Note the composition in the drawing above. The use of receding diagonals adds depth and dynamics to the space. A straight on view of the sink would be far less interesting. Also note the use of dark values in the background to push the objects forward.
