Terry,
The lighting used is strong from the nib side an overhead light would help to separate the background and a stronger light or reflector from the right would give detail in the shadows. My mantra in taking pics in the old days was the more lights the more shadows.
In our studio in the 70,s for ever it seemed I used one flash bounced of the wall for all portraits Wilma and I were in the studio and a visiting mate took a quick pic of us using my simple set up I have shown it before but I will look it up now. This only to show every need can be taken care of with lighting and experimenting as you are now.
Kind regards Peter.
