D. As you processed the images through drawing, what aspects of the artwork did you see accurately? What kinds of information did you misunderstand in your drawings? What does this tell you about the way you see?
So what i did was that I first look at the big picture from far behind, and figure out the big shape of positive space and negative space. I tried to block out the main shapes of the artwork. Then I drew a middle line vertically and horizontally to place the big shape properly on my sketch book. The hardest thing for me was that different colors have same tone or value, so it was hard to translate that into black and white on paper. Because I was blocking the shape and value, so my eyes were only focused on the tone of the paintings.
Personally, I always find the darkest area of the artwork and then I start sketch from it. The benefit of it is that I have control of the darkest area, and then I just lightening up the rest. The downside of it is when the painting was extremely desaturated, it’s very hard to define the value change on my sketch book.
