The vocals definitely need to be stronger.
Punch them up and it'd be perfect.
Really nice! The audio kind of hurt my ears at around 1:10 though. The vocals were a bit soft, but that was okay (with the exception of 1:20; I think those vocals definitely needed a bit more strength).
That was some epic music. Good times.
Please contact me if you would like to use this in a project. We can discuss the details.
