Web magazine Highjinkx reviewed "Postwar does not just take the arrangement or tone of classical music to replace parts of the electronic musicgenre frame, but rather dismantles and mixes the devices of classical and electronic music." Jeong Byeongwook of Indiepostdescribed the album as "The work of a person who realises his concerns and answers between music in terms of enjoyment." Cho Jihwan of Tonplein said the album's trackIonisation as "The track takes models of already tangible styles and creates itself by tearing them out little by little, twisting them, mixing them up, and pasting them together."
