Awesome!
It's a very awesome song in general! It just sounds like a no bullshit raw ass metal song so I can't help but love it! As for what you're saying about the transition at 1:40, I kind of see what you mean. It sounds like it's going to go into something bigger like a crazy solo or something just louder but it turns into just a normal kind of phrase that sort of builds up. It's fine though it doesn't kill the song or anything hehe.
As they always say, there needs to be more of this traditional sort of metal around here! heh
Anyways, awesome song! Great job on this!
