Admirable! Your work is as good as the best I have seen.
I am a fan of strong contrasts, and I love your use of color. I also appreciate your varying treatment of light -- a dungeon, like any other working space, should have good light available whether the the master chooses to use it or not. I also like the slight elongation in the legs of some of your figures. Even after I figured out what you were doing, I still find that fascinating.
Thanks also for working the upper body. What is it with all the feet, anyway!? Some things I just don't get.
If there's one other thing I would like to see that is all too uncommon in the art in this forum is a range of body types. I see some advancement in the art, and I believe your work is another step forward, as in the render with the "nuns" and the, uh, novitiate? The difference in body types does more than the clothed vs unclothed opposition to convey the power relationship at the heart of any fetish play.
But, still, I'd like to see more artists look at the pictures! Where are all of the petite women? Where are all of the slender-as-a-sword ladies, twice as flexible? Where are all of the Friday's/Applebee's/Chili's girls? Where is the occasional nerdy girl, so cute and so desperate as she begins to realize that she is indeed way in over her head?
That'd be art.
