Bittersweet is a series of Eva Liu's watercolour paintings made starting from 2014. Originally, it was Eva’s intention to purely express and record her love for food through her detailed watercolour paintings. As time goes on, she finds that each and every such painting did in fact record far more than that. Certain memories are attached precisely in each artwork in that particular moment in life. This series of paintings is more than just a food diary. It is a reflection of different stages in one's life: some bitter, some sweet, but mostly bittersweet. The series encourage audience to think about their memories attached to certain food and savour them while viewing the artworks.
