That’s a super cool instrumental song, I like it a lot. It is sounds quite accomplished and doesn’t have the boring side that instrumentals can easily have.
The mix is balanced overall, there is nothing that blatantly sticks out in a bad way.
I think what could be improved is more in the recording and arrangement: I would say the drums and bass are probably the weak link here. Your guitar playing is great and the overall timing is perfect, but for this kind of music the drums and bass have to be super groovy and retain some human feel while being super tight, it’s a very difficult balance to strike. I believe your drum pattern is a bit too repetitive and the fills don’t sound quite like something a good drummer would play. There are a little too many tom hits and not enough ghost notes on the snare for this genre in my opinion.
Same goes for the bass, I believe it would benefit from a little less notes but more focused on the groove and there could be a more interesting interplay with the kick drum.
The guitars that play the downbeat 1 on each bar are a bit too repetitive to my taste as well, I believe they could play something less “sharp”, you could save this for shorter sections in the song.
Anyway all of this is mostly a matter of taste so what I gave you is just my personal opinion. It is a great job nonetheless.
