Hmm
Like said before it'd be nice if there were drums. You should look into getting something like Acoustica Beatcraft you an download the demo at www.acoustica.com and it's quite simple to use. You soun dlike a decent player but the quality of your guitar is kind of bad since you just plug straight into your computer without any kind of direct box or something similar. Anyway I've spent most of this review going on about improving your audio quality so I'll get more to the song.
First off Amon Amarth kick ASS! It's nice to see somebody here cover one of their tunes. Any idea which tune you might do next?
Overall it wasn't too bad but could really use some drums. What gear are you using by the way?
