@dburchardt to me, they're more difficult because you have no imagery to pull from, no preconception of what, say, a nose looks like. I get interns sometimes and, to open their minds, I ask em to paint 3 emotions without symbolism, no hearts for love, no gray clouds for sadness....it's amazing what we can come up with but it's far from easy. To include emotion in representational art is some real master stuff. Not possible for AI.
