Fantastic..
It's a shame this hasn't been rated higher. I understand though, this type of progressive ambient/rock music isn't very popular for some reason which is a shame.
However, everything on this track is done extremely well, the multi-layering of synth creates a massive wall of sound that is fantastic which eventually builds up to a brilliant climax.
Mixing and mastering is also done very well, my only comment is that in a few areas you seem to have too much going on in the middle frequency range which seems to drown out the guitar work at some points. Remember that there is only so much you can cram into the same frequency before things start to sound muddy :).
However, this song gets the highest score i've ever given on any song to date on newgrounds. 10/10 man, keep up the good work.
