"style and feel" are entirely subjective.

If I give DALL-E or MidJourney a picture of myself that I took (and therefore I own the copyright), and ask it to "Recreate this picture in the style of Pixar", am I violating Pixar's copyright?

What if I decide to model it myself and deliberately imitate Pixar. Have I violated copyright?

What if I decide to model it myself, and it just happens to look similar to Pixar, because I've watched a lot of their movies and it has influenced how I model people in 3D animation. Have I violated copyright?
