This ones pretty weird for me. It started out pretty fine, there's this weird sound at :15 that just comes out of nowhere and sounds out of place. There's also this weird riser that plays just when the other synth has already played it's part at :43. And it just feels so sudden. Both when it begins and end without a fade out or some sort. A problem I think this song has, with the exception of 1:45, which was pretty ok if you ask me. It feels as if this song was an experiment or something. If that's what you were aiming for, then I have no problems with that.
Then there's this music box-like sound that seems pretty muddy if you ask me during :59, only to be replaced with another music box-like sound at 1:26, which sounds much better than the one previously mentioned earlier. I think if you'd replace the music box-like sound at :59 with the one at 1:26, it would be better that way. There was also this sudden volume change during 1:33 and 1:36.
There's not really much to criticize at this point, except for the end, which abruptly stops. Overall, I think this needs improvement.
