Wow, this surprised me.
I really enjoyed listening to this!
The intro was already very captivating, and the rest kept me from leaving.
I don't really have anything to complain about, this is just so big and full of cool stuff!! How don't you have any fans yet? Let's change that shall we :p
I usually try to point out what's good and what's bad in a song in my opinion, but I'm liking this so much that I'm finding it difficult. I know some might argue that this song lacks coherency, but I like the randomness and all the different parts. Even if some of the transitions are pretty sudden I don't think they have a negative effect, but rahter that they captivate the listener. The production/mixing is just excellent as well!
The dynamic between the instruments is also ridiculaously well pulled off; oh do I envy your talent :p
I also like the way you brought back some of the stuff that happened earlier in the composition at later parts (examplewise what you did after 1:30 and 4:54).
And that guitar bridge indeed!
You deserve many more listeners on this site, and I'll sure you'll get some too, if you keep this quality of work up!
