I don't do post work because I do not have the software..  Photoshop is way out of My price bracket.
Painter X by Corel is all I have..

I take on board all you have to say about lighting,  but,  like i said above My Post work facilities are limited to say the least..

The arm will go to the Most constructive post that points Me in the right direction  (Like this one)..

BTW if I stroke Your ego enough,  do You PURRRRR??
