I think the vocals are a bit too much louder than the guitars.
Possibly too much reverb on the guitar rhythm parts.
Maybe record the guitars again with different amp/cab and mix two takes together for
a bigger sound.
The vocals sound a bit weedy. What mike are you using on them?
I'd do rock vocals on a dynamic mike and not a condensor. Compress them a bit more
and possibly add some delay and a touch more reverb.
There is a definite Iron Maiden sound to the proceedings. See if you can get hold of something off the Piece of Mind album like 'The Trooper' - someone in this band will have it and aim for that sound.
