Sweetness.
My first reaction to those high pitched synths were a bit doubtful, I won't lie. But then I sat down and thought to myself "Why did he do it?". I know by now nothing you do is purely random. At the transition at 0:42, I realized that to carry over to that point worked wonderfully.
Where did you get the cheering sounds? So real! Truly makes the song feel like a dance song, you know, where you rave and dance, and jump, and possibly make fun of other people because their break dancing reminds you of a paralyzed goat... but I digress.
What really impresses me, is this song uses the same foundation melody for throughout the whole song, and yet it never gets boring. The constant changing of the secondary layer on top of it keeps it fresh, and exciting.
It does change melody wise at 2:31.
Oh my god, you killed Techno! ;).
My friend, you need to get a better microphone. When I want to record myself singing or anything, I place the microphone an inch below my lips. Close enough to record the voice, out of the way of the breath to remove that distorting breath noise.
Melodic wise, this song was absolutely amazing. I can see you progressing in skill as I go down the list of songs.
Last minute of the song was pure orgasmic, wrapping it all up.
Breakdown ending, worked out pretty well.
I have nothing to suggest in making this better. Easily another 5/5 from me.
