Been a little while since I was here last, and catching up was such a spectacular trip. JovianJ mostly said what I'd say to you. But here's a bit more: you have a special skill for portraying fairly static positions in a way that imbues them with tremendous energy. The stationary poses seem to vibrate right off the page, as if the damsel had been squirming right up until I looked, and then would probably begin squirming as soon as I turned my eyes away. This is a phenomenal aspect of your work, testimony to the intensity of the emotion and passion in the scene that you've depicted.
Given all the above, I'm wondering if you're going to try your hand at somewhat more dynamic representations...say, a damsel in the act of being gagged, or bound.
In any case, keep up the wonderful work. With your permission, I'm going to add you to my "Watch" list.
