Coming in with what sounds like a nice clean, contemporary Alan Walker-esque mix. I'm not sure about the transition at 33 sec. 0:46 makes up for it.
I would lose a little bit of your reverb for the drops and turn down the kick a bit on the sub frequencies. Sidechain is meant to help it cut through, which it is doing. It's just a tad loud. Perhaps a more subtle touch on the release.
As a whole it sounds not unlike a lot of others in its genre, nothing wrong with that. It means you're getting somewhere! However there is something I feel it lacks to stand out, which is variety, especially for being a long 4 minutes. I think the key change was not necessary -- but to each their own!
What I would like to hear is some more varied instrumentation, ethnic percussion accents, more stripped down sections of the drop earlier on to give later drops more depth, etc. You've got a solid structure and nothing in particular is detracting from the piece except that it sounds like I've heard it before, but I know I haven't.
Beyond that, great work, particularly on your mix. Heavy compression didn't blow it out of proportion sonically and that says a lot. I think you know what you're doing, and in time you will surprise us all with where you're going. Great to hear from you.
Thanks for coming out to NGUAC!
