Oh that intro is clean. I'm upset at how good this song sounds. It's also super happy and bouncy which is also pretty enjoyable. I'm less fond of the 1:10 section though. It feels a bit too bright with the mixing compared to how warm the intro is. Fun and unique chord changes 1:41. The snare doesn't cut into the mix as well as it sounds like it should. It sounds too big to be in the background as much as it is. Once 1:52 comes in, your soft atmosphere is just so warm and refreshing.
Really my big critique on this is when the song gets loud. It's not loud and painful, but I think your mix suffers. I mentioned that it feels bright, and it's probably because you saw synths are too hot in the mix and crowd out the melody. The probably could benefit from some more high frequency filtering. I think the percussion could benefit from cutting through the mix more. I like the soft kick, so it doesn't need to do much more. There's appropriate sidechaining there. However, I've already mentioned that the snare could be more front and center. I really can't tell if you're trying to use high hats or cymbals in that section.
For me this is more difficult to score compared to most NGADM songs I've had to review, because most people produce content in a song that's pretty consistent in the song. There might be some uniquely good or uniquely subpar spots here and there, but not like this. As you can tell by my writing, I think there's sections that you nail it, and it's basically perfect. Then there's other spots were you have a full ensemble of sound happening that suffers in mixing particularly. Which I get it, trying to make a big space while being clean is difficult. My advice is to use reference tracks/songs while mastering/mixing. They'll give you an idea of how your song compares to a professional mix and help you keep in check what's supposed to be in the foreground and what belongs in the background. It also helps keep you mix in check if you're getting, what I'll call, producer fatigue (when you've listened to your song so much that you get used to your mix). This one is difficult for me to give a reference track suggestion, but a couple I would suggest would be Ganbatte by Pogo, and The Days by Avicii. They're not as close as I'd like, but they should be similar vibes.
