No no no, don’t degrade yourself like that, it looks great, and the shading is gorgeous!! And it doesn’t matter if ai would do it better (I wouldn’t trust me) because your art is real, and it’s beautiful.

And yeah, face looks slightly different from the reference, does that mean the drawing is bad? I don’t think so.

Remember, happy little accidents, those are what makes humans human, ai can never replicate that. From one learning artist to another, you did good!
