There can be improvements on this which is to reduce the repetitiveness on the middle part of the music 0:16 - 0:36 and 01:18 - 1:39 and try to put something different in it. But you still keep the beats just don't make it keep repeating the same thing. Though on the 1st part of the music 0:00 - 0:17 I like the transition the calming music to fast pace drum n bass really does add the theme.
