King Arthur Movie Tristan

I nearly died when I read about it in this month's Vogue. I am going to enter! I probably won't win, but sure what's the harm in trying! I am currently looking for ideas about what to write for the 3 topics and I would really appreciate your ideas!

The Topics are:
1. To write about a person memory of mine... events, place or person. (800 words)
2. To write a feature article... cultural review, fashion trend etc. (500 words)
3. To write an opinion piece or polemic... person, current affairs, social issues. (500 words).
