[7] AllMusic senior editor Neil Z. Yeung commended Birdy's "evolution from acoustic covers singer to confident and powerful artist" and stated, that the album "brings a depth that pulls Birdy from Ingrid Michaelson territory and into a scene occupied by Lorde, Florence, and Lana [Del Rey]."

He felt that "with more life, richer texture, and an inspiring attitude, Beautiful Lies is Birdy's declaration that she is more than able to make her mark in the big leagues and join the ranks of the alternative pop pantheon".

[2] Marc Snetiker of Entertainment Weekly gave the album a B+ rating and noted that "Beautiful Lies places her square in the middle of the indie pop realm [...] Her third album is her own testament to talent and her proof that she's only dipping her toe into the tropes of her genre to spring upward from them and float onto a cloud all her own.

[5] The Irish Times writer Tony Clayton-Lea felt the songs on Beautiful Lies showcased Birdy's songwriting abilities, with "telltale names indicating a smart artist getting to grips with the differences between inexperience and hard knocks."

He added that "notwithstanding leaf or two taken from the Lorde handbook, Birdy delivers a special brand of off-centre pop music that directly reference her transition from teenager to adult.
