goood work.
Filtering everything is not always the answer. A few times in the song I felt like u were gonna stop doing the filtered feeling of having half a sound and break it down, and you just did a crash and went back to the same instruments. I'm pretty sure you could make it more epic by breaking away from that.
Beats could be doing more since right now u just have a kick and a clap, with the snare rolls and crashes at the ends and starts of phrases.
On another note, cymbal crashes are good, and can be used alot, but you tend to use it at the end and beginning of almost every phrase and it's also the same one every time. It takes away from it's effect every time you use it. Try to change that up.
Echoes are pretty good, but could be adjusted in diffrent parts of the song.
fading could be a bit more subtle and cleaned up a bit.
Snare rolls could be done better with a bit more growth.
The melody itself is pretty good though. Just things here and there that could use work.
Last thing, the main melody you have is similar throughout, but since u have the slow bits in there as transitions, use those as excuses to change octaves or instruments or stack or something since you only use that one sound during ur more trance like parts.
Let me know when you have the finished product, id love to hear it.
