I don't particularly like thriller movies, but I enjoyed the movie "The Black Swan".
After seeing it I decided to create a poster for an hypothetical musical.
I chose to represent the protagonist as a white silhouette instead of black because she is a white swan that wants to become a black one.
The poster is simply the protagonist daces surrounded by feathers on a purple bluish background which remembers the madness where She losts herself during the show.
I used several tools to make the poster: the swan with Illustrator, the background with watercolors and the lyrics with Indesign, all finished with Photoshop.
I also created the show ticket and its advertising.
