I just listened to bliss. I think it is good. It is a little short, but you did say it is the start of a song, so... The drum beat sounds a bit like it is skipping at times, but I have not decided if that is a good thing or a bad thing as of yet
I could picture it being used as a background track in a movie as it is now, but as a song for general listening I think it would need to be developed/extended a bit more.
