Was able to emphasize only one minute area of the drawing
Was able to create the illusion of depth
Was able to create no difference in texture

lear that the artist was able to create the illusion of depth through the use of value change. However, I'm not sure about the other options. Perhaps the artist was able to make the image have no contrast because they believed in the power of unity and wanted everything to blend seamlessly together? Or maybe they were able to emphasize only one minute area of the drawing because they wanted to play a little hide-and-seek with the viewer's eyes? As for creating no difference in texture, maybe the artist just really, really loved smooth surfaces and wanted to challenge our perception of touch? I must say, artists are quite the tricksters!
