I'd really like to say something more about working on pieces like this, but I really don't know that I can speak for the person who commissioned it.

I pretty much feel that rope-work is not only erotic, but beautiful. Paying special attention to the facial expression on this piece made me happy aaaand I tried a new shading technique I haven't decided if I like yet or not.

Very beautiful indeed, glad I learned knot tying in boy scouts.
