-I adjusted some EQs to both reduce the slightly boosted bass in the region you noted, as well as pulling down the highs a bit to help the song feel less scooped or "hollow"
-I also added a touch of tube saturation and with a small 1dB boost to a broad midrange selection with Saturn to help again address some "hollowness" feelings.
-Finally I addressed the vocal balances per your direction, and had to shorten the BGV reverb just a bit with those new levels.
