Skills Audit for Soundtrack

I opened sound track pro and then I clicked the search tab and then the first sound I used was the "Cowbell with big verb" sound effect and I was going to use this as my basis for all of my other sounds and sound effects. I then went to the violin tab and chose "Contemplative synth", i chose this to give the music an eerie sound. I put a scream at the end of it to finish the piece.
