Target audience

I have been using the social networking site of Facebook, to find out what my target audience like. I have been doing this through Facebook Messenger.

I asked a 20 year old, (who's within my TA) which image they liked the most?

She answered:

Image NUMBER ONE:

(The image I, myself actually preferred)

This qualitative research will help me to design my front page in the best way to appeal to the preferences of my TA.
