I like a lot the composition, and instrumentation, despite being a short piece it feels complete.
The transitions between the different parts are smooth, and good overall mix.
The comp/limiter (I'm guessing) feels a bit too aggressive on the lows.
I like that roll and "rallentando" at the end, but I think the final hit fall short after the tension and epic vibe of this piece, but it's not a big deal. Solid work.
Thanks. Glad you like it. It's indeed rather compressed in the lows. Sometimes I think it's too much, at other times I think it gives the song a little more boost. In any case it was really difficult to mix it with all these instruments at the same time, and compressing the lows was a way to cranck up the overal volume, which I felt was necessary because I want this song to be at a climactic part of my demo album. The hit at the end is a little anticlimactic perhaps. You can also loop the song by having it start on the hit. I think that works quite well.
