Pride

Any time a photographer can create such an excellent image with so much light coming thru the window behind the model, that photographer has done outstanding work. Framing the model with the curtains adds to the quality of the image. I do wonder if the image can be enhanced by cropping from the top down.
You have chosen an excellent model for this image. Her pose, her outfit, and the setting all work well for you to create the image. I wonder what has happened to her left arm. Is there anything you could have done to keep from losing her left arm? Could she have placed her arm across the curtain to her left?
