Just found out two days ago that Null Brainz updated their pixiv after nearly 3 years:

While there's not that much actual new stuff, it's nice to have the complete mahjong tile artworks together in a single set:

This specific image isn't new (was previously posted on tumblr), but it was something relevant that wasn't already posted in this thread.

Besides, save for the eye and bow color, I couldn't help but notice a resemblance to a certain Type-Moon character that I'm very fond of (*COUGH*my-username*COUGH*), in particular this image resembles the ufotable version of how she looks after she's graduated from high school.

And strangely enough, the following 4 artworks that are listed right after this artwork in that complete mahjong tile set are of Type-Moon characters too (images 40-43)...
