Before you get your feedback on your poster you need to begin planning another film poster. You are making one for the other side of the audience. You are making it for the same film.
That means:
- if your first poster is aimed at a male audience then your next one is aimed at a female audience for the same film
- if your first poster is aimed at a female audience then your next one is aimed at a male audience for the same film
You would be advised to keep a lot of the same features, just make the poster masculine or feminine as necessary.
