A full, thorough review
For this review, I'll use my generic review format:
Melody-8
There were some areas where I wasn't sure where you were going with the melody. In particular, the section betweeen 1:30 and 2:00. Honestly, it feels a bit random to me, and it actually took me a while to realize you were still following 4/4 time there because of the way you arranged the melody.
Harmony-7
Let me just say now, many of my comments are going to zero in on the aformentioned section and those like it. The rest of the song is excellent. However, the chord progression in that one section doesn't seem to have a central goal. It doesn't express any emotion or theme. Don't worry, I've written many a bad chord progression in my lifetime, usually as a result of me trying to be TOO original. If anything, you probably shouldn't have ended the chord prog in those sections by switching to an augmented 7th and placing the bassline on a 5th.
Rhythm: 10/10
The rhythm is excellent and carries the song very, very well. Keeps your head bobbing and everything.
Instruments: 9/10
Perhaps too many saws in the beginning, but overall excellent choice of synths.
Mix: 10/10
Every instrument compliments the other. There's not a single problem here.
Mastering: 10/10
And the mastering job is excellent, I have to say. Really good job dude.
Beginning: 8/10
Seeing as it follows the same chord progression as the aformentioned sections I was complaining about before, I can only give you this score. However, you have a very smooth flow from the intro to the main melody, which I want to acknowledge.
End: 8/10
My only complaints are that you should let that last instrument fade out rather than ending it abruptly.
Overall, an 8/10. Good job, I really enjoyed this song. Especially the main melody, and it's as you say, very upbeat and energetic. My main beef with that one section is that it seems to run counter to the theme of the rest of the song. It doesn't seem to fit. But regardless, it's a great song.
