 Describing the song as "gorgeous", Anupa Mistry of Spin magazine noted influences by Solange Knowles and added that "she's cool with being pitchy and imperfect". Ludovic Hunter-Tilney from the Financial Times called its sound "indie-R & B of a downtown variety" that Solange Knowles would record. The Verge's Trent Wolbe concluded that "No Angel" was reminiscent of Solange Knowles'work on the extended play True (2012). Bradley Stern from the website MuuMuse called the song one of the album's more "left-leaning productions" saying that it would sound suitable for Solange Knowles'work with Dev Hynes. Philip Shelburne of Spin magazine found a "distinctly Burial-like quality" in the song. Greg Kot of Chicago Tribune noted it was "[a] s discursive as' Blow 'is insistent". Mesfin Fekadu of the Associated Press wrote that the singer "declares she's a freak" in the falsetto-heavy song.
