Funny article. Since we're nitpicking the shit out of a children's book, I actually dug up my old copy of the book, and the artist has a screwy sense of perspective. Using this, the vanishing point is directly above the cow painting. But the problem is that if you draw a line from the wall corner, it will perfectly line up with the front of the drawer, which makes no fucking sense. Both the bed and the drawers are too "in." The bed in general looks kinda weird as far as perspective is concerned. I think the line where the back wall and floor meet is also not supposed to be a straight horizontal line.
