A lot of people don't realize that AI-generated images tend to make the same mistakes over and over - weird hands, facial proportions that don't add up, anatomically nonsensical details. That's actually a huge *advantage* for anyone who wants to study seriously, because it forces you to think critically about what you're seeing instead of just copying mechanically.
The best way to use this ethically is to treat it as an anatomical and lighting reference, not as a "ready-made recipe". Generate the image, then study it: why did the face end up proportioned or not? How does the shadow define volume? Take screenshots of specific details (an eye, a hand, a facial plane) and work on those isolated elements, mixing them with real photographic studies. That way you're building genuine visual understanding, not xeroxing. The ethical difference is in not signing off your drawing as if it were 100% your own creation when you know it traced directly from it - but learning through that image? That's legit.
Another thing: take advantage of the mistakes themselves. When you notice something off in an AI generation, *draw the correct version*. That's real anatomy practice. And alternate with photography, because the camera captures nuances that AI still fails at - skin textures, unique characteristics that no generation can replicate. In the end, mixing it all together (AI, photo, live observation) is what develops your eye. 🎨
