Before you finish take my advice.
How long is the final version going to be? So I will list the good and bad I hear so far.
1) Some nice delay on that lead sound. I'm talking about that 1st sound at the very beginning of the song. Keep that in effect.
2) The intro drums honestly suck. It ruins the whole mood and makes me just want to stop listening to the song. Change them.
3) 33 seconds the song gets better however! now that you got two sounds going at once you must make sure they are in unison. So you got the higher pitch (I will call it "A") sound and a lower pitch sound (I will call it "B" ). Careful listening and you can sense the unison is not there. Solution: Lower the attack time of sound B a little bit so the sound aligns with sound A.
4) Song works well at climax. Bass makes everything sound better.
I think you should just trash the first 33 seconds of the song and start the song at 33 seconds on. Your decision to take my advice or not. A respectful 8 stars.
