An article on Reddit was published showing the difference of art style after season 4. When I was brought on Family Guy, my sole directive was to make the BG's sound, perspectively correct, readable, make shapes more in the style, and workable in layout. Before 2006, you might notice an inconsistency in style, and after, it may be apparent that a style is established. That was my assignment. I'm still unhappy with color and value choices- but I was vetoed.
