When I’m browsing around pixiv and something that jumps out at me with its colors and style, it usually belongs to Fuzichoco. She comes up time and time again on pixiv’s staff picks blog pixiv Spotlight with her modern take on traditional Japanese themes. She even made the box art for her favorite drawing program, openCanvas 6, and she has an online store.
