I love doing press! It doesn't matter if it's big or small because in the end, it helps promote the film, all the people who worked so hard on it, and let's the world know you are passionate about what you do. It also shows the filmmakers you truly are a team player.
P.S. Always good to check in with the filmmakers first in case they have other press lined up.
"Guerrilla Film Scoring" is an invaluable resource. I do not make a penny from this but I highly recommend this book as myself and several other working composers are interviewed about the actual day to day practice and not just theory of scoring for film, television and video games. A #1 best seller on Amazon in several music categories it is a must own for every composer.
