I really like the intro sounds, though I'd widen them a bit. The snare is pretty good that you have, I'd maybe add a touch more reverb though.

WOW, I was NOT expecting that change at 0:37, but I really like it! I think it may need more mid section like an additional pad in there to fill the space, but it's a really cool idea! For example, when those gorgeous arps come in at 0:49, there's nothing accompanying them to give the track more flow...do you know what I mean?

Here, I'll give you an example. In Kasbo's track "Kaleidoscope", the arp in the main drop has enough accompanying it and it acts as a means to fill space as well, as opposed to an outright lead. Here's the track for reference, the arp I'm referring to comes in at 1:40:
Other than that, I agree with carlitoNthecokefactory - the lead is a bit too loud and drowns out the kicks, but it's a solid track so far! :)

Nicky Romeros Kickstart Vst is very helpful with sidechaining

for just a by-the-numbers tutorial, here's a video of how you'd sidechain using pro-c. i dont personally use pro-c, i use a peak controller (which is arguably more convoluted), but that tutorial should get you where you wanna be.

also, some things that help a lot with getting more control out of sidechaining:
dont be afraid to sidechain only specific frequencies out. (i.e. you can drop out a whole bassline, or just the lowend)
use multiple SCs for individual instruments (smaller ones on the lead/pads and larger ones on the bass, etc) to let things breath more
use shorter samples, like a trap snare or white noise, to trigger the SC so you can adjust the release yourself.

It's an ok idea, but i think the repetitive nature kinda is off putting.

It's tough to see where you'll take this just as is. you could of developed an entire song with just those sections you have. all you'd really need is the transitions.

and IMO the transitions are the toughest part of any EDM song.
