I found the cutest website, it's artist Bill Zeman. His daughter (tiny art director) tells him something to draw, which he does, then she critiques it. It's hilarious to read and so cute! Not to mention the drawing are pretty good too. Check it out! Here's a taste:
The Brief: A dinosaur in a X-Ray
The Critique: I just want to see a little mousey in his tummy
Job Status: Approved (after addition of mousey)
Additional Comments: That's what kind of bones dogs like to chew on. Dinosaur leg bones.
