Truly heroic!
I have to admit that you have managed to out do A Shade of Autumn with this one. Normally, I don't get to do song reviews, but thought that one for you was needed.
Instrumentation: I really like how you had NES samples and real drum samples together with this. Those really complemented each other and I think that more people on the Audio Portal should try mixing chip samples, electronic beats, and actual instruments together.
Composition: I also enjoy that melody that you had, and the rhythm going on set a heroic tone for this without being bombastic. It takes a careful hand to make something heroic without it going overkill. The only other person that had done this was Xenith800 with his song Sun God.
Other: The only two faults that I can find are the fade out at the end and the file size. For the former, It gives it a seamy feel, which makes it feel like it belongs in a flash movie rather than an X360 game. Second, I understand that you want that high definition sound, but you may want to consider the Ogg Vorbis format for high bitrate music. Then again, seeing that Adobe didn't include .ogg support, I won't take points off.
What I do like:
-Nice harmony with the samples
-Heroic melody
-Great rhythm and tempo
-Original
What I don't like:
-Doesn't loop properly
-The filesize, but I won't be harsh since flash doesn't have Ogg Vorbis support.
Overall: KgZ, How would you like a ten from me? One more thing, I think you Audio Portal musicians should team up with people in the Flash Portal.
