Question 2: How effective is the combination of your main product and ancillary texts?

The choice of form works well here. There is a lot on her outfit and how this relates to her but it is not about a textual analysis  of her, make sure that you are looking at the fact it is a Promotional Package and how you used the techniques you did to help an audience relate and ultimately buy into your artist. Think institution and also the ancillary is a magazine advert for an album release not a poster.
