Ambient music is a genre by itself.. It can sometimes just be 'audio wallpaper', soothing, not really going anywhere. I'd be tempted to add some subtle tidbits to it. I 'think' a hear a cello line there somewhere in the mist. It might be nice if it rose up just a tiny bit, stated something and then backed into the mist again.. Perhaps some slight 'tinkles'.
I am not familiar with Hammock. And if it was your intention to work in that vein, well that's another thing. I think it's OK to copy other bands, as an exercise in discovery or your own music. or learn some new techniques, absolutely nothing wrong with that. I appreciate that you tackle different approaches in your uploads. GOOD
