This project discusses liminal spaces as an aesthetic. Each illustration is related to a specific kind of core, and through these posters, I aim to depict the unique feel and atmosphere associated with each core. The cores I have chosen to illustrate are weirdcore, which conveys a sense of confusion or comfort and often evokes nostalgia or uneasiness in its viewers; dreamcore, which immerses its viewers in the sensation of being inside a dream or even a nightmare, where unrealistic elements are visible; and lastly, a poster that combines both weirdcore and dreamcore, labeled as 'liminality.'
