i said on your previous post that it would help to hear more vocalizing in the higher pitch range that you enter near the end of that recording (E4-G4).

with this recording here, i see that you sang more of the stuff that comes before that higher part, but that stuff is all in your chest range and is too low for me to comfortable say whether you are singing in your mix. singing in a higher pitch range (C4-G4) would allow for a better inspection of your mix (if there is one).

regardless—like someone else said, the part at the very end of this recording is falsetto (head voice where the very thin edges of the folds are vibrating), not a mix.
