Mixing studies seems to have payed off nicely 😄, sounds really great! The track itself is great, so I can only mention a couple of probably pretty subjective things that i felt on my first listen:
Like Prospero mentioned, the guitar feels a slight bit too upfront/overpowering the melody parts, felt ok at the beginning with just alongside the bass, but after the synth lead comes, it felt like the guitar is fighting for my attention from the lead synth (not totally sure if just lowering the volume of the guitar might help or EQ).
One other thing I felt that might have been cool, was that if the marimba was on the left instead of the right, since the lead synth already plays there, so it would have given a nice change to have the melody "change" ears and give the marimba its own spot in the "stereo field".
From what I've listened to the soundtrack, you nailed the vibes on this!
