Good image ! although,the pose likes a little bit unnatural,forced,but I suppose that is a part of the staging. I think,that the contrast among the dress and the colour of the space increase the spectator interest as such as this kind of  composition, by the way very much effective.Maybe,if we  do the crop that I'm showing you also will work as fine as your original frame.In my opinion we can avoid  a part of this hugue area that is over the model, without changing nothing important,or relevant...Only it's an opinion.Best regards

This is great. The contrast of color makes it work and the scale of the room. I wish I had made this picture.

Great modern artistic picture! A classic of the modern photography!

i like the idea of the shot and much of the result, yet i dislike the stair rail on the wall intersecting the model, the barrel distorition visible on the column and i also find the left hand to have somewhat of an undecided position.

Wonderful composition ... well done !! Best regards

Wonderful work. Simple yet attractive.  Several elements work well for your perfect compostion  Lightling wise, the bright light fades genently from the window leading towards the model who is wearing black, making her stand out of the image.  Composition wise, it makes the viewer walk through the entire image, from the window through the stairs to the model.  Lovely. One thing  I do agree with Mairo on his version of eliminating some of the empty areas. Overall, Excellent. Bravo. 7/7.

Beautiful lighting and well composed image.
