3. I admit that I don't do things as how it's supposed to be done, because many times when I wish to find the excitment of the piece, I would just detail out the head or the area of focus point first to get the strong feeling of the subject. In order to pop out the main subject, you can use either color, detail, and/or push up the contrast to do it. Since I have the shape in dull green, now I'm gonna use a bit saturated dark red as the darker tone, and cold blue as the lighter tone, because the color in different value acts kind of opposite to each other, cold aginst warm, or dull against vivid. Colors will pop out to each other.
