Chris "Flict" Aparri (credited as "Flict") handled the production for the three tracks. The three songs were recorded at Windmark Recording Studios. Composition Music and lyrics Musically, Reflection explores a variety of musical genres. As noted by Matt Collar, of AllMusic, the album spans "electronic-infused dance music to synthy, rhythmically bumptious hip-hop to retro-'90s R&B."

The song "Brave, Honest, Beautiful" contains portions of Destiny's Child's "Bootylicious", co-written by Beyoncé. The group also praised the singer Mariah Carey on the track "Like Mariah", produced by J.R. Rotem with samples of the hook on Carey's 1995 single "Always Be My Baby".
