This is a tough one. Maybe a little too tough to take on for your first restoration out of the gate. The restoration that you created may resemble the person in the photograph, but it no longer resembles the photograph.
With that said, this certainly displays the fact that you have considerable skills. Not to mention dedication, because it looks as if you spent considerable time on this. However, if I were in your shoes (and I'm not ... I gave up restoration due to lack of skill), I would start from scratch on this image or throw it back into the pool. If you throw it back, grab something less challenging so you can feel the success that you deserve. Then you can always go back to something that will test your abilities.
There's no shortage of challenges in this line of work.
