nice image, like the sepia tone, and the flatness of it works well, good title - meets the model's expression, also like the movement of the pen. Good Job :)
Nice pose, composition, and lighting. Wish for some eye(ball)s, i.e., looking at camera with an interesting expression would be best, but I'd settle for more visible eyes not looking at the camera, especially for a posed shot.
Nice composition and sepia works well. Well focused. You captured your subject in a studious pose.
The image lacks a full tonal range. Try this... set a black point at the darkest spot in the composition and you may find the image will maintain its current tonality but will have much better contrast and will stand more. It is a little "flat" as it is currently. In photography there is a constant battle between tonality that shows nice gradations from one tone to another and contrast which washes out tones. It is hard to find the happy medium.
