Look at this flea, and you'll understand that what you're denying me is very trivial. The flea sucked my blood first and then it sucked your blood. Now our bloods are mingled in the flea's blood. This mixing of bloods is not a sin or anything to be ashamed of. The flea now grows big with a new life inside it.

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.
