21: The World Tour received predominantly positive reviews from music and entertainment critics, who praised its production value and genre-blending setlist, as well as Starr’s vocal ability, stage composure, and rapport with audiences. Timi Sotire from
The Guardian awarded the concert four out of five stars. Sotire praised Starr's "vibrant
vibrato" and her "
synergy with her band and dancers," contrasting her show favorably against what she described as "lacklustre concert experiences from some of her Nigerian counterparts." Sotire described the set as "an ethereal experience", but noted pacing concerns, writing that the hour-and-twenty-minute runtime "tests the patience of some", and that "tetchy shuffling breaks out towards the finale, taking the gloss off her biggest hits". She also referred to the closing
Whitney Houston tribute as "corny".
GUAP observed that she projected "self assured confidence and star quality", maintaining audience engagement through "a mixture of beautiful vocals, sharp choreography and vulnerable anecdotes".
NSS Magazine's Jason Kwame emphasized Starr's commanding stage technique, describing her as someone who "struts boldly" and "owns every corner of the stage" while maintaining "record-ready vocals on stage – full of trills and passionate high pitches." Commentators found certain moments to be especially impactful. Starr's
a cappella rendition of Patsy Cline's "Crazy", performed from the Koko balcony, was one of such example, receiving particular acclaim from both
1883 Magazine and
GUAP.
NotjustOk, covering the Toronto set, wrote that Starr "shows off the impressive range of her voice while delivering this amazing song", pointing out that she rarely gets the opportunity to do so due to the pop and afrobeats focus of her catalog, but that the stripped-back ballad gave fans "a treat". Guest appearances during some performances were also highlighted by
1883 Magazine as having "further elevated the show’s energy," while Starr’s closing rendition of "
I Will Always Love You" was interpreted by the same outlet as "a message to her fans and supporters who have been alongside her journey thus far". Reviewers also framed Starr as a rising force within transnational pop music.
GUAP called her "the embodiment of her name – a true new age pop star," adding that "if her show is any example of where the rest of her career is to go, her future is extremely bright". Contextualizing the tour as her first headlining run at age 21,
1883 Magazine concluded that she "has the quality that will undoubtedly put her alongside some of the best to do it" and affirmed she is "a star in every sense of the word".
We Plug Good Music considered the show "a testament to her strength as an artist", and commented that she "portrayed every aspect of being a true pop star". Meanwhile,
NSS Magazine opined that her vocals “are strong enough to go toe to toe with any [male] in her genre." Beyond formal reviews, the tour also attracted attention for Starr’s fashion choices and stage persona.
Legit.ng documented social media backlash after her Stockholm concert, where she wore a pink two-piece outfit with a cropped top and satin mini-skirt. Responding to male critics on X (formerly
Twitter), Starr wrote: "A bunch of useless men in my CS telling me what to wear and what I shouldn't [...] everything I do is for the girlies [...] you are not the target audience! Disgusting." The exchange prompted wider discussion about
double standards, with one fan arguing: "Y'all condemn her but praise
Cardi for dressing similar [...] the double standard for African men." Audience reception across most stops was documented as enthusiastic, with Starr consistently engaging with fans.
QCity Metro reported that during her Charlotte, North Carolina stop, she told the crowd they were "one of [her] best crowds so far" and indicated that she would “definitely return to Charlotte" on a future tour.
We Plug Good Music found that Starr "regularly interacted with the audience" and that such moments "bridged the gap from fan and artist", with the writer observing that she "used all the space on the stage, making sure to make eye contact with her fans on either sides of the room, and not neglecting the people up on the balcony".
Style Rave covered a widely praised scene during the Hamburg show, where Starr left the stage during "Rush" to interact directly with fans, "holding hands and taking selfies with them". The publication pointed to the time when she knelt beside a disabled fan in a wheelchair while singing, calling it a "compassionate act" and one of the night's most memorable experiences. When asked by
NSS Magazine to name her favorite stop, Starr replied that "the love [she] felt in London was exceptional," while still maintaining that "every city holds a unique energy". == Set list ==
