i'd crit but.... I don't think you can just post the .aup file---

theres no audio files (.au) and it can't be opened. in audacity you should export as .wav or .mp3 and post that.
very nice guitar work man- great rhythm and some killer riffwork. your playing is superb, i say with drums and some production this will sound really solid. excellent use of harmony and multi-tracked guitars. the chorus definitely had a touch of in flames, as for the rest i'm not familiar with arsis but it sounds like you got it down.

if you got to crit one (no solo yet but its coming),
