The "guitar-synth" in my left ear in the beginning sounds too mono, think for this kind of music it should sound really eery, some more depth and reverb to it...make it sound a tad more distant. The mermaid/siren synth is really nice, but yeah you could have it sound fuller too. Like you said, it's all standard sounds, think you should spend more time on digging deeper here. I would lose the organ-like synth and replace that one by something else, it doesn't really fit. Choir pads in the background really nice, suit the track well...I always like that kind of pads. Well yeah I suppose this was a track to discover the abilities and sounds in Ableton, you got a nice beginning here, think now's the time to dig deeper into this one. Spend more time on warmer synths or at least try to give more flavour to the track, it sounds too mono/hollow/dry whateva you wanna call it ;-) Also, the ending should be a lot more worked out, I was like "huh...that's it?" I sense some oriental vibes here, goodgood, maybe you could replace the "acoustic guitar" from the beginning by some Japanese plucks, I dunno...just some thoughts huh.
