Judging a book...

So i bought this book a while back,
it's a required text for us to have next year.
But i have to say, why on earth would they allow the cover to be like that?
Come on...that's like messed up proportions even for a Hotwheel.

(The Star Wars book came this morning, it's intense! I'll probably paint a couple of starfighters soon. Watch out Vaughan!)
