0:00-0:24 was quite good, but when it comes to adding lots from 0:25-0:48 had really went off on the wrong foot.
0:47-0:48 was really weird how it took a sudden turn from one mix to another. Might want to change that part a bit to fit it perfectly.
The ending from 1:06 ended quite awkwardly, maybe try to extend the beat before trying to shut it down.
