Not bad, but this isn't really my style . . .
I'm all for the progressive thing you have going there, but I do think the riff in the beginning needs to be a lot more aggressive . . . Well, overall, the whole song needs to be more aggressive. I just think it needs to pack a lot more punch than it does as it is. The melody should only sound a little louder than the accompanying bass line and counter melodies. Your melodies stick out way too much for my taste. Nice arps though.
Also, the second little riff you had going, I think the second riff you had going on at about 1:16 seemed like it didn't harmonize well with the rest of the song in the last half of it's duration (you know the last half before it loops over) . . .
Good work anyway. You have some good ideas going on here!
