Re: Sample + Flip -- That old school Wu-Tang style type beat (Japanese sample)
You made good use of silence with your main theme, in the sense that the alterations counter what would otherwise be boring. In other words, the use of silence prevents this theme from being boring and enables it to have that floaty, meditative, chill-out feel.
You seem to have a good grasp of when to vary and diverge from the main theme with sub-sections of music and how to weave a smaller theme into the main one. However, I did get a little worn out at around 3:06. Loving the snares and the beat—these do bear repetition quite well.
