The comic was drawn by the Muecas team, which consisted of actual Shenmue project members.
Actually, アニィたかはし (Anii Takahashi) who drew the comic was not an official Shenmue project team member, but one of us, Shenmue fans. Muecas-dan was formed by the official Shenmue team to communicate with fans and the fans who contributed to their web magazine were acknowledged as Muecas-dan members. Anii-san was the first fan who got the honor and awarded #011 as a Muecas-dan member. Myself got #023, btw. ;-)
Here's the last Muecas magazine and you can find the member list in the left column:

Anii-san who was an amateur cartoonist back then now has become professional and even published a comic book like this:
