Audience feedback

To ensure that I get reliable audience feedback from the right sources, I facebook messages over 20 young adults that fall into my target audience to look at my music promo so they can then message me back telling me what I could improve on and why, as well as what they think is successful within my work. It is important that I ask both males and females, as my chosen artist is a typical Alternative genre which is popular with both male and females. It's really important that I take these comments into account as small changes they suggest will help me to refine my work and improve upon it.
