You have done a very very interesting artwork here ^^
First, for the light effects, where all action is half lit by those torches and they gave an red/yellow light that add a very creepy or eerie touch on the scene.
This makes the guy´s position looks even more lonely and away from any help... even i think he does not want any help
The guy´s puppy outfit is also fascinating for the all-body tighty suit design, shiny like latex, and is all tied... with the tail stucked between his legs and turned ahead...
and finally the dominatrix. We see is in the control but she does not let her face be visible, immersed on the darkness... who is she? Wadda does she want? And the whip.... looks like there is a LOT of pain... and pleasure oh yeah
