Overall I like it! Very seamless transitions.
The volume in the beginning of the piece I think was a tad to loud. When it transitioned at 0:25 I feel like I had to kind of struggle to hear all the layers of instruments playing.
1:36 I really liked the volume swell, it drew me back into the piece.
From 2:30 to 2:50 it felt like there was a lot going on, kind of disorienting, but it did give that very ominous feel. However I really liked the transition at the very end.
I am new to the site though so take all I say with a grain of salt, haha, Nice work my friend.
