Couldn’t find the artist’s name but he goes by lordampersand online. The medium (?) is ink and watercolor. From his Mastodon feed:
“Research for this piece has provided a name for an aesthetic I’ve always been fascinated by: “Liminal Spaces”, the depictions of places in-between.”
You can see his sketches as this piece progressed here. From his website:
“i’m a self-tought artist from switzerland. my drawings and paintings are usually analogue (ink, watercolor). i’m fascinated by the interaction between organic and technological processes, the things that grow and the things that are built.”
