This is very interesting. You definitely got the suspicious feel down, that you do. It has just the right speed, and just the right sounds to go along with it. So for what you were going for, you hit it right on the nail. I would love to hear this in a video game, I'd know to watch out for something for sure. I think it'd be better if you carried out the beginning sound alone for a little longer, if this is meant for a video game though, since you carried right into the song I feel like it's not as suspicious as it could be. Anywhom, 10/10 5/5, very nice job.
