Wenjun Lin is a game development artist, illustrator and comics artist based in Shanghai.
There is a portfolio on Character Design Reference, and another on Art Station
I don’t know specifically which projects the images are from, but most have a delightful, innocent childrens book illustration vibe and a playful anime spirit.
They’re lush with high-chroma palettes — often of analogous colors — fun details, and fanciful, imaginative world building.
There is a Wenjun Lin art book titled Ghost, available from the French bookseller, Liberdistri, and a brief YouTube thumb-through of it here.
