Zeentober is a 44-page large format hardcover artbook from freelance illustrator Zeen Chin who's based in Malaysia.
This book features the ink and pencil sketches created for Inktober 2020 but Zeen Chin didn't actually use any of the prompts. All the artworks are character sketches of this sexy lady with fantasy elements. The art is amazing and is at the same level as Kim Jung Gi.
His earlier artbook is Re-Child which is also terrific. See if you have the chance to get that too.
