Have you read 2001 Nights? I don't know if it's your thing but the art blew me away.

oh yeahhh, years ago. Certainly something I should revisit.

the art on the book is fantastic.

2001 knights creator Yukinobu Hoshino also did a series, i’m just reading about called The blue hole

  “about the discovery of a gateway in time and space deep underwater which allows for travel between the present day and the age of the dinosaurs. Its title in France is Le Trou Bleu. It was serialized in Mister Magazine from 1991 to 1992 with two tankōbon published
“

also there’s a review of his artbook here that looks really cool
