These are just some basic ideas I put down, I'm not dead set on any of them. The first section (measures 1-16) is more inspired by the score of The Thing (1982). The second section, measures 17-32, is more inspired by the score of Psycho. I have rough drafts of the script but not the final script, so once I have that it will be easier to set down some ideas that will fit.
