Usually I would delete a picture like this. But this time I had to use it because the Model was very shy so this was the best one I could get so I had to deal with it
To focus the picture I used the middle cross-sensor and focus on one eye.
While editing I gave it a try with the Adobe RAW converter which leads me to a satisfying result. I chose a new image section which set a better focus on Trudis (the name of my hairy model) face. Then I calibrate the picture step by stet by using the sliders. I start with the first one on the top and end with the last one on the bottom. I used exactly this sequence and I was surprised because with my old camera (Eos Rebell 350D) this was not possible.
The final picture:
