The majority of younger people (<35) and some people under 50 draw in a style that is either reminiscent of newer Disney cartoons (Aladdin, Lilo and Stitch etc), reminiscent of anime, or reminiscent of 90s Nickelodeon shows. A lot of artwork done by younger people since the end of the 90s has been like this, but then if you look at the bulk of what people were drawing before 1997, and almost all of what people were drawing before 1985, most people were either drawing in the style of classic superhero comics, the style of classic newspaper comics, or the style of comics such as The Beano. A large portion of people currently aged over 40 still draw in these styles, but fewer younger people from my experience. The most notable difference seems that cartoons of people have more emphasis on the eyes now than they used to.
My question is on what accounts for the change? Have styles changed very little but the technology has improved (allowing for smoother line art and better colours), or have styles evolved as well?
There is also a trend I've noticed: In the 80s/early 90s, most people were still drawing in a "traditional western" style. Then from about 1997-2010, a lot of the stuff people were doing (look at an archived Deviantart homepage from 10 years ago) was anime, and now we are seeing more diverse styles, often with elements of both Western and Eastern (think of the Disney style).
