This has the potential to be a great shot. The colors look great and give great tone to the shot; however, some things that could potentially be done differently might be changing the depth of focus, it may be the monitor this is being viewed on, but the model's face doesn't seem to be as sharp as the rail she is standing in front of, the other thing that could be done differently is the model's position in the frame, she could be further to the right since she seems to be looking off to the left, it is traditionally considered correct to place a larger portion of the shot off to the side in which the subject is looking.

Wow! You have really thrust yourself into the art of portraiture and fashion portraits. On a personal note - I am so proud of you!

You caught a terrific pose here. It is greatly complimented by her eyes and facial expression. It reminds me of those old paintings of young women waiting for their men to come home from their long journey at sea. The fact that there is a great deal of motion from the wind cements that image in my mind!

The colors are perfect, with hints of colder tones that contrast her warm skin tone. I like the tone her skin has, the subtle reds work well to make sure she isn't lost to the background. Had her skin looked to pale, she may not have stood out from the railings enough.

My only critique is that for me, there is too much at the top of the image. I would have cropped it a little closer.. but that is all about personal composition taste.

Great work! I can't wait to see more portraits from you.
