You definitely have some great back-lighting going on here- and nice rim lighting too! Back lighting is a broad term meaning the light is in the rear of the subject or coming from behind the subject. Rim lighting is when the light behind the subject only captures its outline. Well done!
Thank you all for your vote of confidence. I have done better but still not entirely pleased with my results. It will come up again and I will try again but not right now. I appreciate you all.
@olivetreeann Thank you for your kind words and the explanation. That makes it a bit clearer.
