What have you learned from your audience feedback?

To get my feedback I posted my video on Facebook, which is a social networking site. Posting it on here my friends will watch it and they can post a comment underneath telling me what they think of my video. There is a button which you can click on Facebook to show you 'like' a post, 11 people clicked this button to show they like my video. Although many people liked it not all off their comments where useful. One of my friends said she liked how the picture ripped and showed the singer on a bench by himself, in the rain. She also added that my actors guitar skills was unrealistic as he cannot actually play guitar and that the singer wasn't always in sync as I used on of my friends rather than the actual singer, so he didn't know the lyrics. Another commented congratulating me on how well I planned out each of the shots and said that it really showed. One said more emotion could have been added as it looked like my actor had a smirk on a lot of the shots, which contrasted with the conventions of a Blues music video. Finally, one of my friends said about the shot where the actor is in the toilet staring at the mirror, he said he liked how I implied him being sick rather than showing it, leaving it to the imagination. He also said that he liked how it was slightly ironic as the lyrics in the song is, 'I keep my mouth closed,' as he is being sick. All in all I found my feedback very useful, I had a lot of good feedback leaving me confident that I have done well. But, as I only posted it to my friends they are less likely to be straight with me and give me bad feedback, so I should of posted it somewhere where I can get feedback from people that I do not know so they would be a bit more blunt with me and give me some criticism.
