According to www.dictionary.com, fine art is:
a visual art considered to have been created primarily for aesthetic purposes and judged for its beauty and meaningfulness, specifically, painting, sculpture, drawing, watercolor, graphics, and architecture.
After reading the definition of fine art, it is almost impossible to refer to William Blake as simply an illustrator. By calling him an illustrator one would be assuming that would be his main talent or expertise. In class we spoke about what a "renaissance man" means and William Blake would definitely be a renaissance man. (Meaning he does a little bit of everything.) He was involved in: illustrating, typography, owning his own business (printing), engraving, book publisher, poetry, and painting. Personally, I consider illustration to be quite an art in itself so my answer to the question of "Is William Blake a fine artist or an Illustrator?" would definitely be "fine artist." His work is captivating and he is a fine artist if I ever saw one.
