Hey, I'm new too! Checking out others' demos and reels to see if I'm swinging for the fences a little too hard or not.
I dig your track! Nice vibe. I wish I could hear the early iterations to give a second (third?) set of ears to your mix changes.
I use Logic, but recently tried this free saturator and can't say enough about it. It's not the prettiest w/ the giant DONATE button on it, but it adds color and oopmh without touching a thing. Sometimes, though it can be a little strong on bass, so I usually dial that back. Follow it with an adaptive limiter and you can get some good consistent volume in your mix buss. http://www.shatteredglassaudio.com/product.php?id=104
Secondly, if you're still in the market for feedback - the lead is a little loud to me. It's also spread into the left channel more than the right so I'm tilting my head a bit to hear it.
If I were mixing (big if), I'd push the kick and snare like a dance tune (I saw the J-pop tag, so I'm going to invoke some Megurine Luka and Yasutaka Nakata here). Then I'd gently compress the lead voice to even out some peaks in the high end. The smoother that lead can be with a driving beat, you'd have a good head bobber, like a light-hearted Eschatos vibe. I'd turn the bass up a little too, I'm sure that's doing interesting stuff but I'm not hearing it that well (and I'm using Bose buds that really hype bass!).
I love the direction, though, and can see it in application. If you're just starting out with mixing, you're killing it already! If you're a little more advanced, I can see this as the turning point in your development.
