Personally i think a improvement would be to remove the constant "clapping" that you have from the start to end, it will make the tune more ambient and to be honest it kinda annoyed me as it sounded out of place and broke the ambient.
However the tune overall sound ambient and maybe even a bit horror-ish, i could hear this in a horror themed game with boss battles, something like silent hill perhaps.
So 3 and a half for me, good luck on your future projects.
