Music Video Audience Feedback

I conducted this survey in college at lunchtime. I asked 100 students the following:

1) Did you enjoy the video?
93% Yes 7% No

2) Do you think the video reflects an RnB song?
100% Yes

3) Do you think the video looks professional?
83% Yes 17% Could be improved

4) Would you change anything about the video? If so, what?
85% No 15% Add more scenes of artist doing other things e.g driving

5) Do you think the video accurately reflects the song?
100% Yes

I feel that the results of this survey are very important as it is fundamental in the marketing of a new artist to use audience feedback to make improvements, however as i conducted it in college, I was only able to ask a small age group (16 - 19) of our demographic and feel that if I had conducted it in a public place and included older members of the audience, the results would be more accurate.
