Sounds really great, the basics of Latin music, i would only change the piano, it sounds like Brazilian music, and better use a Cuban tumbao.
This gives me the idea of a haunted house. It's really scary and lets you forget about all other things in live for a moment. The part from 1:00 is a little worse in my opinion, but it holds the scary feeling about it. I think this song is worth 5 stars.
Please contact me if you would like to use this in a project. We can discuss the details.
