Stay and watch the credits the next time a movie finishes. Many 3D artists work in live action productions, adding visual authenticity to streetscapes and buildings to match a film's historical era or geographic setting.
Look at the biographical information provided by publishers of graphic novels. Movie studies such as Pixar and Dreamworks provide links to featured artists. And don't forget fanart sites, where young artists post their work in the style of their favorite artist; they sometimes link to that artist's website or blog.
Find examples of 3D art online. Bookstores and libraries also have Anime, Manga and Graphic Novel sections which feature 3D art. High school and college art departments periodically announce gallery shows with 3D artwork. Art instructors who have worked in Hollywood or for major game developers also show their work in galleries or online.
Search websites where 3D artists post their work. Websites also offer 3D stock models, which an artist can license and customize, saving time and money.
