Some things I was able to put my finger on after looking at a bunch of the images in the feed:

• It doesn’t do skin well, treating it more like a smooth plastic than a surface with pores, wrinkles, and fine hairs.
• It doesn’t understand lighting, so shadows don’t agree with highlights or even each other.
• It doesn’t understand anatomy. A lot of the images were fine in this regard but others had misplaced muscles, bones, and impossible limb positioning/truncation.
• It has no idea how to draw vaginas. Nipples are also not well understood, though it does better on average with those. They still look more like a plastic than skin, but most of them were passable at least, while I didn’t see a single vagina that looked even close to right.
