Hi Kevin. This is a really good question and feeling comfortable dealing with these details can take a lot of practice! Essentially, for that particular section (Part III) you want to focus on how things look, more than on meaning or symbolism. Not all questions posed will necessarily be relevant; consider what is applicable to the examples you've chosen. For line, ask yourself if the painting has lots of straight lines and hard edges or are the lines more blured, curved, and soft. Is there a harsh light or a soft light? For balance, unity, etc, think of the composition. Do thigs seem chaotically arranged, drawing your eye in many directions? Yes or no, is the result created by color? The organization of different elements? Light and shadow? I hope that helps a little bit! Does anyone else have thoughts or suggestions for Kevin? And, Kevin, please feel free and ask follow-up questions. I'd love to continue this discussion!
