It was the acoustic performances and Lewis' vocals that garnered the most praise from critics; however, there was a mixed reaction to some of the arrangements such as the reggae influences on "Better in Time".

[5] During an interview with Digital Spy, Lewis told Tom Eames that Glassheart has a running theme about "star-crossed lovers that can't be together", and so it was likely that this idea would feature on the tour.

"[8] Barclaycard ran a competition which gave fans the chance to win tickets to 6 May concert at Birmingham's National Indoor Arena.

[11] In a review for the Express & Star, Elizabeth Joyce said although Lewis was not like her contemporaries: "meat dress-wearing" Lady Gaga or the Russell Brand-marrying Katy Perry, "no one can reach those soft lows or soaring highs quite like her".

In particular Joyce praised Lewis' performances of "First Time Ever I Saw Your Face" and "Bleeding Love" which earned her standing ovations, in addition to the "note perfect" rendition of "Run".

Hollisey-McLean praised the decisions to switch the song arrangements, for example adding reggae beats to "Better in Time" and performing the acoustic version of "Trouble".

[13] The Guardian's Malcolm Jack was less impressed; he stated that when Lewis tried to diversify the show by dancing or switching the arrangements, she risked becoming the British diva that pop music forgot.

[14] Jack said that during a "sassy dance routine" for "Forgive Me" Lewis came off as a "budget Beyoncé", whilst on the "cringey windin' and grindin' reggae take on 'Better in Time' song" she comes across like a "reasonably priced Rihanna".
