Roland... 
has chosen a very difficult photo for his job.
The background is dark and very confused.
The color of the skin of the keeper...
  is very dark and little detailed.
the hair are very difficult from cutting 
and in the low side of the photo,
the subjects are confused up to become an only black stain.

Very good the idea to change the background... but is too soften
good the buttocks
but... poor little definition
good the shadows...
there is a little error on the shade of the stool.
All the picture must be...

sharpened...

This is My solution
