Very well done. The detail work is exceptional. I would like to see a more defined light source and add a little more dramatic lighting. A light source from above the faces and off to one side would add more drama. By that I mean maybe a little more contrast between highlights and shadows. Other than that, it is excellent. I like the gray background which allowed you yo bring out the highlights on the skin and clothing. The drawing technique obviously demonstrates a high level of sensitivity and a light touch. My compliments on this wonderful drawing and I like all of your work.
