Ach!
Chorals + synths + computer = horrible.
When doing chorals in electronics you really really really have to work hard on the articulation, vocal depth and variation in tones or it just sounds flat, like this one does.
The sudden stops don't help either.
The theme is calming enough, but it needs a lot of work before it will really go anymore. Chorals like this need a lot of depth and feeling behind them, as well as very careful weaving of the different elements. You have to really work on the smooth, calm of it and use more, lighter vocals.
Varying shades of the same colour, if you will. It's really the only way you can do it. The current backing and foreground is too limited and contrasting to work properly. That combined with the poor application of vocals really doesn't make this song sing.
However, the human voice is a goldmine, dig for all your worth and you'll miss it, but apply a bit of learning, understanding and time, and you can hit a jackpot.
Work on this, you have something there, it just needs a lot more work.
