You tell us again that you don’t know how ambiance work! This is stunning.
The background noises like the wind, birds and waves are beautifully paired with the droning strings and droning voices and here and then some dulcimer glistening thru. I can’t even believe that this is made with mostly free samples. You definitely did some GREAT work. The ambiance you’ve created just begs the listener to stay a wile longer and just soak it in.
While you said you wanted to implement some more FX, I don’t think this is necessary. It is a beauty as it is.
