Media showcase stats: Suggestions and complaints

We have received the answers from the media showcase.
These four questions were given to the audience to answer about every video they watched.

1. What did you understand about the narrative? (Quick synopsis, please):
2. Did the chosen genre fit its conventions?
3. How did the "ending" make you feel?
4. Any suggestions for improvements, if we were to shoot the whole thing again?

Upon collecting this information I have written up some statistics.

All together we received 38 filled in and partially filled in responses
Out of these 38, 23 had suggestions of some kind


I was able to group the suggestions/complaints into 4 catergories
1. Lighting issues
2. Bad camera quality
3. Speech quality
4. Unique suggestions

This piechart that I made shows the percentage of suggestions we received
