The model and your photography is amazing. This one really is striking. She is well posed and in a respectful manner as opposed to a more sexual way that many would do in this case. Well done indeed.
I only have one slight critique; that is the back ground colour (bright yellow) that appears like a halo around her head does not transition well and looks like rings. It may just be my monitor, but is a bit of a visual distraction if part of the photo. It is almost like the sharpening and noise reduction blew out the bright colours.
Having said that, I think it is a great work of art.
