Excellent vibe and composing, really selling the vibe here!
Is that Valhalla Supermassive?
I think the mix got a little murky - which can be very hard to tame. Still something I'm learning more about myself. Overall the mix is good, but it has a lot of midrange resonance that could probably use some EQ and compression.
I'd say this one really correlates to the theme exceptionally well. It has a strangeness to it that sells it, with the lushness of the synths (as described below).
Really love the synths you picked. Absolutely fantastic work. :)
