Sometimes I think the acceptance of anime came since most teachers got used to the idea that the style was here to stay. Purism... can be good, when you want to stay true to the roots of a movement.
Now that anime is no longer The New Hot Thing, and carbon-copies of Dirty Pair or Rayheart no longer draw attention like before... new forms of art seems to be growing, I'm seeing a lot of korean influence and more attention to anatomy and colour.
But here we are in a very interesting position. We have a lot of influences from everywhere. Personally, I have american (Stuart Immonen, Jon Bogdanove, Frank Frazetta), european (Gustave Dore, Alfons Mucha, Jean Giraud) and asian (Katsuya Terada, Katushiro Otomo, Hiroshi Minagawa) influences. I built my style looking for lineart that could convey a lot of detail and ligthining, I liked how other artists created textures and volume only using black ink. And you may say that my main problem at this moment is balancing the color with this particular lineart style XD
I think our problem it's that we became in love with those new (to us) styles and we embraced with passion their aestetic before taking our time to understand their whys and hows. A lot of the expressionist work (and art noveau too!) started with a philosophy in mind, with an intention and goals.
It seems that we are just past our teenager's crush with oriental art and starting to look for a more mature "relationship" with art, maybe looking to grow beyond the surface of the animu and start to understand why we fell in love with this style in the first place.
Sorry, it seems that I'm able to pull out essays too...
