Don’t worry, lighting is a lot of trial and error. In the end you try and try and try, you change and change, you experiment and experiment, and it’ll never be perfect, and eventually what we do is just let go and abandon it all. Like the great quote says:

One mistake we often do is we want to show everything, we want to show the translucency, every little thing we modeled, that little detail we put in, but the truth is we have to learn to let go in service of the best framing and composition. If you want to showcase your work, you don’t have to do it in a single image, you can have multiple cameras and multiple light setups that accentuate different parts of your model and have a couple different renders.
