No offence to you or the model but there's a photoshop quality to the portrait. Somehow, to my eye, the proportions of the models face are unusual- especially the eyes. The skin tones look like they have been worked on too. Again, just my 2 cents.
What a wonderful way to start the day: your photo caught my eye immediately. A stunning model indeed, but I really admire the composition of your work. It is always well balanced and the models look their best in every shot.
I continue to be extremely impressed with your work. The majority of photographers attempting high key in the digital age suffer from blown highlights, lost texture and tonality. . . all of which you avoid with style and consistency. The pose and cropping are right on the money, the use of diagonals with model's arms, her overall stance, and even the crop of her hose top are textbook perfect.
The only, and I do mean only, thing I can think of to suggest would be to address the stray hair on the back of her head in post processing, but it certainly is not necessary.
A beautiful, film like rendering of yet another beautiful model.
