Gets off to a great start!
As most of your songs do. Very peaceful! I love that chord at 0:53! 1:12 was interesting - I can hear a hint of Tool. I like 1:29, and I want to be able to get into 1:29 (I can feel myself almost headbanging), but I think the complete lack of bass and the tone of the guitars deters me... The tempo slowing down around 2 minutes into an ambient part is a good idea, but that part just wasn't epic or long enough for that to sound good (in my opinion). I would suggest putting a crazy breakdown or heavy part after 1:12 and before 1:29... I think it would flow much better - then continue on into the ambient part or fade out, etc.
Sounds great! Has a lot of potential!
