ok so youve definitely got some chrono trigger/final fantasy vi/majoras mask vibes with this one. i love how dark and moody it is, i love the atmosphere you got goin on, i love the low THUDS at the end of the loop...
if youre goin for vgm, is this area music or encounter music or cutscene music
if its area music maybe slow it down a little more and tone down the wind sounds a hair- fade em in and out maybe. they get grating after the first twenty times. this could get repetitive real fast if yr doin some caves of narshe shit with it.
if its encounter music you could make the tempo faster and the low drone build up to somethin. maybe throw a drum solo in there.
if its cutscene music you dont gotta change anything its a great ambient soundtrack and its creepy as hell. id think about how snes dialog bloops would interact with it- like would they be out of sync or distracting or whatever.
