With over a decade of experience in visual design, Cheung Siu Ching (Maf) later ventured into the art and illustration field. She is a former committee member of the Hong Kong Society of Illustrators.
After founding her art brand Matey Mori, she has been dedicated to integrating art and design, with works spanning across brand identity, advertising campaigns, and digital media.

She has provided creative consulting and art direction for large-scale projects commissioned by government bodies and international non-profit organisations, while also collaborating closely with a range of commercial brands to develop product designs and marketing strategies that balance aesthetics and market appeal.

Since 2022, she has been working on her illustration series "Hong Kong Giant Animals", and published her first art book, which received an enthusiastic response and quickly sold out during its debut at the Hong Kong Book Fair.
