I like the way, in both this song and "Through Space," that the different melodies all have a cohesive relationship with each other so that the transitions cycle within an infrastructure that represents a solid theme. Everything is exactly where it needs to be and doesn't feel "short lived."
The only thing I would suggest to change is the dynamic gap between the bass and leads. There seems to be too much empty space between the two when they cooperate, as if they're trying to talk to each other in different languages. There should be some kind of middle man to smooth it out. Maybe even the drums could fill such a purpose.
Also would like to mention again I really love "Through Space." Very well done song. Favorite part is how the drums enter.
This is the best review I've ever received.
As for the "gaps," I'll try to work on filling those in. Thanks!
