I think the mix is pretty spot on for the quicksand deftones reference, very dry and easy to listen to and easy to discern the separate elements. Two things stand out to me as not quite there.
Singer guy is no Maynard or Walter and is really kind of a bummer considered how melodic the band is, I would seek more opportunities to drench those vocals in ambience, verb throws, flange, delay... really any creative thing you can think of to dress it up and make it less one dimensional.
The snare is a bit flat I think. Something as simple as a high shelf or a small boost up top would really help it come out a bit.
I think the guitars are perfect for the style. Maybe a touch more kick? Im listening on headphones so it could just be me. Also if you really want to go for the classic quicksand thing you would throw a slow analog style chorus on the bass lol
