The cover art is by Jeffrey Oh and the interior illustrations are by Paul Abrams.
I'm slightly puzzled by the drawing of Sarek. The armour he's wearing is clearly patterned from Sarek's costume in Star Trek III but otherwise he looks nothing like him. It seems odd they would use source material for only part of the image.
If anyone's in the mood for some colouring please do so and send me the scans to post!
