What you describe Binnur is known as 'short' lighting, it can (usually) suit a female subject, making the face appear less 'wide' - however, now you have raised it and made me look closely, here are my thoughts - since Jean has not had time to respond to my challenge (maybe next time, eh?)
The fill (
camera right) is perhaps a little too bright, that side of her face is actually quite bright - in some respects this is just as well because the position of the key light (perhaps a little too low camera left, it is also quite a hard light - see nose shadow), the angle of her head and her features have combined with the hard light to produce some weird toning across
her left cheek.
However, I know how easy it is for a model to change position and suddenly the intended functions of all the lights (key, fill, rim/hair) goes completely 'out the window'. So while I am mentioning these things, I do so with some sympathy.
I suspect Jean and I are at a similar level (in?)competence
(no offence intended Jean)
I feel that I could so easily have produced a shot that looks just like this, or worse!
One lesson I have learnt reviewing this (and remembering back to my own mistakes) is that the harder the light source, the less forgiving the lighting set is for a model changing his/her head position from how it was when the lights were set up.
