If you ask me the word "style" is misused and underutilized to be of much use to people discussing something as vast and varied as art. Currently the way "style" works, is people will group a bunch of artists based on trivial common ground and then slap a "style" label to it with whatever word that happens nearby. Now when you hear that word, you think of one image in your brain to summarize a bunch of people. Most people think for instance Indy style = Black and white autobiographical comics with chicken scratch linework.
When it should actually mean Indy = Independent = Self made
OR Anime style = Big eyes, tiny noses, high saturation, cute shit
When it actually means Anime = Animation in Japanese = Animation from Japan
An actual USEFUL way to define "art style" would be by motivation for instance: Expressionism
was a modernist movement, initially in poetry and painting, originating in Germany at the beginning of the 20th century. Its typical trait is to present the world solely from a subjective perspective, distorting it radically for emotional effect in order to evoke moods or ideas. Expressionist artists sought to express meaning or emotional experience rather than physical reality. Realism
in the visual arts and literature refers to the general attempt to depict subjects "in accordance with secular, empirical rules", as they are considered to exist in third person objective reality, without embellishment or interpretation.
( By the way the most people who use the word "Realism" use it like "oh hey I was trying to make this look realistic" and most of the time they aren't even close. The only reason I see them using it is to flee from being labeled "anime artist". Therefore acknowledging a error as truth and then using an other error to make sure their feelings don't get hurt. ) Cubism
was a 20th century avant-garde art movement, pioneered by Pablo Picasso and Georges Braque, that revolutionized European painting and sculpture, and inspired related movements in music, literature and architecture. In cubist artworks, objects are broken up, analyzed, and re-assembled in an abstracted forminstead of depicting objects from one viewpoint, the artist depicts the subject from a multitude of viewpoints to represent the subject in a greater context. Caricature
is a portrait that exaggerates or distorts the essence of a person, animal or object to create an easily identifiable visual likeness. In literature, a caricature is a description of a person using exaggeration of some characteristics and oversimplification of others.
See a pattern here? There's motivation, reason, to explain why it looks like the it does. Now what's the motivation that dictates how the art will look behind "anime" "western" "comic" "webcomic" ? These are either nationalities or formats, they aren't ideas, or motivations themselves, therefore I won't acknowledge them as "styles".
I see plenty of artists I can ascribe no "label" to, and really how necessary are these labels??
