Looks like a forgot to review this earlier!
It's cool to see a new collab between you, after quite a while. There's a lot of neat things going on here, and I recognize both of your styles in this! The production sounds quite good :O
The thing that stands out to me on this track, is the movement. There's a lot of rhythmic elements going on, and the progression catches the listener of guard in a good way. An example of a surprising spot is the transition at 1:18, which leads to 1:26, which is aslo a really interesting part. I love that alongside the melodies, there are a lot of other things happening too, on the sides or even in the background.
Percussion is also used in quite a liberal way, which is seen at 1:40 and on.
Still, despite everything, there is some nice repetition too. The sounds are really good for you having used only native fl plugins, btw :O
I love the lead after 2:30, personally.
Another great thing, is how TL's interesting rhythmic style, and unique melodies, are fit into this track. I'd almost call it a melodic track as well, even if there's a lot of rhythmic elements going on, and despite the melodies being a bit avant-garde. Though not the first thing one thinks of upon hearing "harmonic", it all sounds pleasing to the ear.
I think the ending fits the purposes of the track perfectly, as well. I don't really have anything to critique here!
One thing I didn't directly mention is that I love the atmosphere this track gives off, since it's a bit hard to place. Great job, to the both of you! I'm hoping to hear more fruitful collabs in the future :)
