I could wish for more nuance in the drums....
The instrumentation was clearly masterful, but the drums lacked dynamic and had too blank of a grind. You could have made things more complex with the ride without giving up that good double bass massage sound.
Syncopation is your friend, and not just in the slow parts. You can syncopate extremely quickly in a pattern so fast it can be used as a piece of a straight pattern. It's easier to understand how a line of melody fits into a chord, but rhthyms kick ass that way.
Blah, I'm preachy.
Yngwie Malmsteen all the way.
