A) She is wearing a redish orange top with an interesting hair do. Her interesting outfit symbolizes an interesting personality.
B) The background is a plain black, making the subject the main part of the piece. The plain black may tell us that the subject is a plain, not fancy person. It is important to understand the background of the subject to understand the entire painting.
C) The artist wants the viewer to know that there is a little bit of pain in the subject's life. I draw this conclusion by the sad and blue look in her face and slumped shoulders as well as how the painter used a lot of color and emphasis in the face and shoulders.
D) This is Heather. She is the daughter of an average family but something has caused her pain. She wants a smile on her face and cares about fairness. Her eyes look as if they're saying, "Don't cheat, be fair."
