DiTerlizzi cites a variety of artists including Norman Rockwell and Dr. Seuss as major creative influences. "Many good fantasy artists will tell you their influences are Frazetta or Boris Vallejo. Realizing this, I went for more diverse influences, since it seemed to me that most current fantasy work has that same oil-painted feel." DiTerlizzi was influenced by artists such as Hieronymus Bosch and Leonardo da Vinci to early 1900s magazine artists to classic children's book illustrators to offbeat modern fantasy artists. Another inspiration was David Trampier, who illustrated much of AD&D's first Monster Manual, which DiTerlizzi recalled as his favorite book as a child: "I would copy Trampier's drawings over and over." DiTerlizzi was a fan of role-playing game art long before entering the field. DiTerlizzi is also a fan of the work of Hans Christian Andersen, Charles Perrault and the Brothers Grimm. Illustrators such as Arthur Rackham, Edmund Dulac, Kay Nielsen and Ernest Shepard all had an impact, as well as author/illustrators like Maurice Sendak, Shel Silverstein and Richard Scarry.
Career
Upon graduating, DiTerlizzi moved to New York with his wife Angela and began a freelance illustration career working for TSR's Dungeons & Dragons role-playing game. "I was so psyched when I got a chance to work on . My entire goal was to 'blow away' the other artists. It helped me in getting the job for the Planescape setting." DiTerlizzi worked on the 1994 Planescape Campaign Setting and its supplements, redesigning the look of the Outer Planes, "Not only buildings but the people had to have a rusted, organic look. This seemed to come naturally in my art style. When I went to work on Planescape, I looked at anime and Japanese fantasy art like Yoshitaka Amano." According to Shannon Appelcline, the artist's work was the backbone of the setting. DiTerlizzi continued to work for TSR, as well as White Wolf Publishing's ' and ' Storyteller games, and illustrated many cards for . He also illustrated books such as 1997's Giant Bones by Peter Beagle, and 1998's Dinosaur Summer by Greg Bear.

Mary Howitt's classic poem The Spider and the Fly, which became a New York Times Best Seller, was his next project and for which he was awarded the 2003 Caldecott Honor Medal.

Dark Horse Books published Realms: The Roleplaying Art of Tony DiTerlizzi in 2015, with words from DiTerlizzi and a collection of artwork and photographs spanning his early career. “Tony's work has a distinct flair, a love for monsters if you will... His creatures have the charm of Henson or Rackham but they carry with them hints of their own ecosystem... Tony stands alone as a world creator and a weaver of tales, may you treasure these art pieces as much as I do,” quoted Guillermo del Toro. DiTerlizzi wrote and designed Star Wars: The Adventures of Luke Skywalker, Jedi Knight, published in 2014 by Disney Lucasfilm Press. Accompanying his words were illustrations by Ralph McQuarrie.
