Target audience and ideas for cover photo

My target audience is going to be teenagers to young adults (14 - 30). I think this is a good audience to aim for as the majority of people who buy music magazines are in this age group, and these people are the ones most likely to like the sort of music i'm going to include.

These are some photos similar to what I would like mine to look like. Quite simple make up and hair, and quite a fun pose.
