This song has pontential!
I like the dark slap bass to the progressive beat. You should consider changing the piano slightly, it plays some strange chords which(i think) doesnt fit enterely with the simple bass. Your choice. A synth in this sound would be cool. You know, like a filter enveloped saw. That could be awesome. Good song, has a lot of potential.
Please contact me if you would like to use this in a project. We can discuss the details.
