Hey now.
It's a nice score. I think the delay effect on the piano was completely and makes it sound like a cheesy mid 90's house tune.
I think you really could've built upon the theme a bit more. The horns do a good job of bringing melodic variation. The end doesn't really reflect suicide at all imo (finishing on a major chord in a minor scale will do that though). A different, more sinister final chord would have been nice. I would suggest AbMaj7/C (Ab Major 7th with C on bass) seeing as your tune is in C minor, but try others.
