Well, it was interesting. I wanted to take this specialization because I do create content for a living.
So, I am thinking perhaps the course was just not right for me, maybe its because I'm a visual person and I can create strategies, as long as they are visual.
Also, you should consider modifying the assignments. Since the more important assignments are peer-reviewed it gets deeply disappointing, as you do not get a guideline of how it is going to be graded, but you get one of how you should give the grade. So, I think the exams should have a higher percentage of the final grade than peer-reviewed assignments.
Overall because we are students, and just follow guidelines. We do not fully understand everything as deeply as the teachers do. So, if everything does not look perfect there, we simply cannot assign a grade. This happened during both courses I took, not only this one.
Moreover, many students do not even bother in reading the assignment, they just like it or don't like it and then, the grade relies too much on how lucky we get with the person who has to review our work and if they empathize or not with what we are writing and the topic we shared.
Lastly, the language barrier, it was harder to understand, write and express my ideas and thoughts in English that I anticipated :)
