Honestly...
I think you may have overmuted the track. If you make that high... sounds kinda like a square? lead stand out more you'll have a pretty ace track on your hands. It's a bit too mundane, even for ambient. Sounds like the problem is too much wet reflection and not enough dry reflection on reverb effects or perhaps just some poor EQing, not sure. That's my opinion, anyway, maybe the song's exactly how you want it as it is :)
