Film poster

Its a poster for a movie called SAFE. This movie show a story of a man who want to erase all memories on his dead wife. Its kind of Sci-fi, trhiller, drama movie. BTW, I have to continue practicing my ability to draw with pencil. Its not familiar to me jajaja.

What kind of texture I could use in this poster? more or less.
