I wasn’t aware of this guy’s work...
I saw some Monet/Renoir stylings, some Van Gogh, Rousseau, Gaugin, Cézanne, then some proto Matisse, Chagall, Picasso, Klee and Kandinski in his work. He seemed, no disrespect, to get less talented as the years went by.
According to Wikipedia: "He was a founding member of Der Blaue Reiter (The Blue Rider), a journal whose name later became synonymous with the circle of artists collaborating in it."
I like best his work with animals in strong, non-linear, designs. I'm not much into pointy things. I find that I almost always like the balance he brings to a piece where, with some artists, I'm always wanting to crop them. I'm also into bright colors, so that appeals to me, too. He would lose me when he goes completely abstract except that, again, I find the balance of most pieces very pleasing.
In addition, his work strikes a very strong bell because some of his early plays with suggested line and shading are EXACTLY the way my mother was taught to draw. My early childhood was spent watching her do linoleum blocks that look amazingly like his wood blocks. But, again, such a wide range of styles that I float into some that push my buttons and then hurry through the ones that don't.

Thats Expressionism. Its about the juxtaposition of color and the rejection of realism. They were influenced by the Fauves, or vise versa, dont exactly remember. Matisse was a Fauvist. Expressionism grew out of Impressionist movement, iirc.
One of the pictures I DIDN’T include was his portrait of Rousseau. I also didn’t include his blue period Picasso lookalike. And I wasn’t that fond of the horses in the pasture image that sold at Sotheby’s for 24 million.
Interesting video - I would have sworn I was looking at more than one artist!
