MacDonald points out that the forest backgrounds were imagined and not drawn from nature; they thus lack the "infusions of warmth character" that distinguish the books that were drawn and painted from the Sawrey woodlands. She concludes that it was impossible for Potter to clearly write about or draw her subjects without some sort of inspiration close at hand. Judy Taylor and her collaborators on "Beatrix Potter 1866-1943: The Artist and Her World" conclude that "Timmy Tiptoes" is "an uneasy book" and one in which the animals do not fit naturally into the background.
