This is surprisingly different with an interesting lead voice - I'm guessing it's an electric guitar with the volume being caressed into producing nice long notes - but I may be entirely wrong?
I like a lot about it and it has great promise.
There were some very cool sounds in this song. I liked the mix of instruments and the mood changes. I mostly write lyrics, so I'd like to team up with someone of your skill-set. I thought of vocals that would go along with some parts of your song.
