The sound design on this one seems a bit all over the place. You have some really good ones such as the guitar that comes in at 1:50, but then you have some like the percussion starting at 0:30 and lasting until 0:59 that sound really out of place and basic. The mastering sounds pretty good, though. It sounds like you tried really hard to not let your sounds walk over the others, even for the quiet ones in the back of the mix. Even at the parts with a lot of instruments playing, it doesn't become very muddled at all, unlike some of your other tracks.
