Was talking to some people about what make's Frank's work stand out. One is the man is an artist with a capital A. He understands light and composition, he understands anatomy and draws people in dynamic movement. Man has the skills and the knowledge to make it all work.
But the other thing we came up with, is Frank Frazetta fucks.
Like with many fantasy artists, everything is really flat, the characters are clearly models posing for the artist. They're just representations of people. But Frank is painting actual characters, and he's 100% unreasonably horny about it. Dude fucks, he knows what people look like when they're running around naked, he is good at drawing caked up dudes, he knows how to tell a story with the way people are moving, the way they're placed in relation to each other.
