Composition is very dream theater. In that respect it's tough to do prog metal nowadays without sounding like a knockoff, they did just about every variation possible (and well) in their long career. That put aside, great arrangement and playing. Lead guitar work in particular is outstanding. It kept my interest for the duration, and that's no easy feat. lol
Mixing things...
Not a fan of the cheap synth sound. You might be able to modernize it a touch with stereo chorus, make it move a little in the mix rather than sit sterile dead center. Add a touch of distortion to it as well?
The bass guitar is, at times, a little muted. Could use more guts/balls when it's more alone in the mix (those few slower moments).
The rhythm guitar tone choices are good but maybe scoop a little of the lower-mids (150-300hz?) from it, just a touch too muddy sounding. This will allow the bass guitar to come through a little more too.
The kick drum could come up (could use a little more low end thump as well), and overall the drums feel too far back in the mix. Compressing the entire kit and/or just bringing it up more in the mix would help.
Once issues in the mix are addressed, do some mastering. It sounds pedestrian by today's standards. Think
METAL!
