Oddly I get some more PS1 or PS2 era games vibes that are reminding me of some dungeon crawler games like Kings Field (though with a more modern sound). The atmosphere you’re creating is quite intriguing and feels like a mix of mysterious and adventurous (hence the dungeon crawler comparison I guess). Your sound choices also fitted that very well and lets my nostalgia heart melt a bit. The general mix is solid, but I feel the master could use some fine adjustments (keep in mind this is very much nitpicking and should be seen as general recommendations and not as a critique). The lower mids do sound a bit stuffy at times (specially when more instruments are playing at the same time like at the 2min mark). Additionally, the high mids are a bit shouty for my ears, specially with the lead synth entering. So my recommendation would be looking into the ranges 450-800 hz and 2k-4khz and dipping some frequencies just a few db, possibly even using a dynamic EQ to keep those frequencies with other situations.
