I’ve gone through this lesson. I did add additional shadowing at the chest as it looked like it needed some darkness added. I keep going back to the Principal BSDF and saying to myself that I like that image better. There is a problem with the eye that the iris is casting a shadow. That can be fixed by moving the back of the eye up to the iris. I am going to post both and a split image.
With all that said, the texture painting does add to the Principal BSDF version as well. Clothes are in Texture Paint in all images.
