I agree with you and it's something you can compensate for. Depends on what your goals are. Are you unhappy with the morph, the texture or both? Suggestions: Keep the splines for the outside of the head very tight when generating the texture. This will avoid dark streaking in the texture. Lighten the texture some in the texture variations area. They do tend to generate dark. Get the texture applied first and then work on the head morph, making that outer spline the shape of the skull. Don't think you won't have to do postwork on the texture.
