portrait Perrine

Others may want to comment on whether they agree or not, but I am thinking this image is almost in key, but not quite.  I think your image could improve if the eye were not led off the page with the lighter jacket.  I also whitened her scleras and the catch lights in her eyes a bit as well as adding some subtle vignetting to the image.

Nice image. I personally find her hand a bit distracting and awkward... it doesn't seem naturally placed. It might have worked better if you had asked her to turn slightly more toward the wall.

Disturbing expression, disturbing composition.

I like it.

(If however that was not your intention it's time to reshoot...)

Maybe a tad more depth of field or focus a little more to the back?

All the best,

Matthijs.
