this is the second song i hear from Ana,

i love the more mellow vibe of this song.
has something of Sia and Adele. i really like what when did with this song.

the structure works well. the build up to the chorus is strong .

the lush reverb is stunning and the vocals take strong.

Constructive feedback :

the only thing i would not is i would love to have a bit more variation in the production. the beat seam to be a bit too repetitive to me. i would love to really have a huge build up in the last chorus. the strings are really nice and could use a bit of a push to really shine and come out.

but overall all "Pull Me Under" is a super strong track!
