The artist Sumisu (すみす) has a delicately intricate style that I often associate with many Japanese Pixiv artists. Their graphic work often stands against a white background, drawing you into the isolated character and setting.
Personally, I adore their shapes and “toy box” subject matter. And I would suggest full viewing if you want to see any of the real detail and beauty.

Note: This may be inaccurate, but I thought this artist did (or does) go by Rinji Umisu as well.
