I think the use of detuning to create the ambience here was really interesting, and the lightly used percussion helped keep a softer feel while driving the tracks forward like in Swim Away. Read through the comments a bit, and I agree with the comment about the reverb. I understand that it can create a really cool effect that can almost feel like another instrument, but you do also want to make sure you dont have the feedback so high as to the point it starts to muddle everything else, as you can have that gorgeous reverby sound that can add to a work without causing as many mixing problems, which is what i think alpikespot was trying to say. Good work though, really did enjoy this! Just trying to clarify more what turning down the reverb could accomplish without sacrificing much of your personal vision :D
