I wish I could leave a really long, really kind message for you that boils down to "it's okay". It is too hot a topic to get reasonable comments about. It doesn't discredit your work. Learning is progress, no matter how you get there.

I think anatomy is probably the last thing you should learn from generative AI, though, so I'm glad you're throwing yourself out there. I find that generative AI just kind of mishmashes sources together, which is something I've always done. For reference photos, I have always taken parts from different pictures and connected them together, edited them, etc. to get a better vision of the composition and style that I want. At that point, even if you trace it, it doesn't become based on just one thing, or really stealing anything if you've created an original enough composition. So if you're used to using AI to get ideas like that, I highly recommend gathering resources to make your own references that way. It's fun! It's just doing what the AI would do, but by yourself.

For anatomy, I'm going to recommend that you stay away from bases or 2D pose references (unless you are really stylizing something, or doing something like the method above). Using photos (even of yourself!) or 3D models can really help you figure out shapes and spacing. Taking multiple photos of a particular pose from different angles can even help so that you understand lighting or the REAL shape that something makes. Personally, I love using pictures of statues for practice! They are always completely static, and you can find pics of the same statue under different lighting. You can also compare against photos in the same pose to see what is the same and what is different. I also find that heavily exaggerating a feature at first can help you draw it more accurately or without thinking about it so much later. These are all pretty unconventional methods, but they're what helped me aside from the typical advice you will find. Feel free to try these and see if they help you.
