The soundtrack itself sounds nice. Better than with the singing so far. You've got it in some places: at 0:47, in the middle laugh part and in the end, almost. The use of this acapella is not linear, you have to make the selection of only vocals you need, which fit at least rhythmically with your song. And it can be one. Just need a bit more concentration onto.
