Shreddage is one of my favorite E guitar synths.
Some things I would recommend, spreading out your guitars more -- double-tracking the rhythm with the A and B options in Shreddage, and panning them 100% L and R respectively with slightly different amps or cabs. This will help create an illusion of space.
The mix and arrangement somewhat harms the feeling of space, despite nothing being terribly wrong with your E guitars. Having used Shreddage for 10 years I can identify the single notes in the high octaves chugging along at slightly different velocities. I think more FX was needed there, more modulation. I can easily identify repeat notes, and it sounds a bit naked and clean. Sounds balanced slightly more to the left channel.
That said the arrangement is great, it just sounds like a few of the guitars are out of balance, either hiding in the mix, not doubled, or just slightly too loud without having been panned strongly enough. Other than that I have no complaints.
Also, the master is very quiet for such an energetic and happy track!
Otherwise, great work!
