According to the review aggregator Metacritic, Stillness in Wonderland received "universal acclaim" based on a weighted average score of 84 out of 100 from 7 critic scores.[10]Pretty Much Amazing's Mick Jacobs praised the song composition in the album, writing: "Her compositions, like Ajikawo herself, defy expectation, transitioning mid-track to blossom into entirely new flowers."[9] Christine Clarke of Now commended the album's lyricism and themes, writing: "It’s clear this is Simz’s version of Lewis Carroll’s Alice's Adventures in Wonderland, only darker and full of imagery springing from the city rather than the English countryside. When spun by Simz’s deft lyricism, Wonderland takes on many forms."[12] Kyle Mullin of Exclaim! praised the album's production, such as the "elephant trunk trumpets and joyfully funky groove" of "Picture Perfect" which "evokes Missy Elliott in her prime", the "hypnotic, techno-ish groove" of "King of Hearts", the "jazzy horns straight out of a vintage noir flick" of "No More Wonderland", the "irresistible [...] radio-smash-ready upbeat synths" of "Shotgun", the "funky, reggae-tinged" "One in Rotation", and the "flamboyantly funky sax sample" of "Doorways + Trust Issues".[7] Writing for The Observer, Isa Jaward concludes by writing "London-born Simz speaks candidly about love, growing up and intuition as she journeys down the rabbit hole of self-discovery. The album’s mix of soul, R&B, grime and trippy, jazz-tinged interludes is at times a little muddled, but Simz’s lyrical agility and deft rapping sit comfortably with a variety of production styles."[8]
