C) "This data is totally useless and doesn't help us at all in solving the problem."
I have written a similar essay. Except it was multiple pieces completed by two different artists. I would say start with the intro, then write the similarities in the second paragraph, the differences in the second paragraph, and the conclusion. If you need more paragraphs to reach requirements then do this:
1. Intro: give brief background to artwork and artist and write thesis
2. Similarities in technique
3. Differences in technique
4. Similarities in emotion conveyed
5. Differences in emotion conveyed
6. Conclusion: summarize comparison and rephrase thesis.
*no idea if this answers your question*
You should start with listing the different ways you want to test them. Then each paragraph should talk about each different method and the results. Hope this helps.
