maybe put some reverb with predelay on the guitars and cut of some high...just a little. Maybe it will help creating some depth.
I agree with the Wave sound..try some automation with the wave sound...let it disappear after the intro and return for the ending and maybe in some middle parts...
The guitars sound nicely. I really like the harmony. Maybe the ending could fade out a little sooner? Unless you like that harsh ending...Or put some Delay with automation on the last Chords...or leave it the way it is!
