in my experience it really has very little to do with whatever it is you're drawing or want to draw, it has to do with your relationship with yourself in the moment of drawing. A lot of the time "redraw hell" (if I were to agree that exists) is more a manifestation of forcing the process and needing the result to be a certain way out of insecurity, anxiety, exhaustion, or time limitations.

I believe creativity is strongest and most smooth when you remind yourself of what you want your result to be, or remind yourself of the "why" behind what you need your vision to be. Do you need the result to be good, or do you need your result to say or express what you want it to say or express? To me there's a very clear distinction when I'm redrawing the same shapes, like, 10 times on repeat, vs redrawing something 10 times in 10 different ways to try to figure out the proper expression of my vision.

Whenever you're forcing the process, you always lose sight of what the result is supposed to represent. As a result, the process becomes a representation of needing to avoid failure, to avoid dissatisfaction, to avoid perceived judgment and shame. It stops being about what you're drawing and why you're drawing it, and instead starts being about self-soothing.

Redraw whatever the hell you want, how many times you want, if you think what you're redrawing is a more satisfying result for your expression. However if you're redrawing something because you're just trying to avoid a bad result, or bad judgment (even self-judgment), I'd say sleep on it and take a break.
