Well, I don't exactly know how you achieved the overall black backdrop (I have my ideas, but maybe wrong), but the framing darkness and the revealing strands of her hair, dark eyes, beautifully toned skin and nice simple catch-lights in her eyes have a sensual (sensory? Sorry, English is not my first language) balance that really beautiful. Look this image while squint: the proportions and colours are pleasing even if you cannot make out any detail or feature. I'd say I'd have a bit of "hair light" in other circumstances, but her hair colour and the background are so well washed together that it would be a serious mistake to separate them. There are some marks on the hair to show them and give an idea about hair volume.
I checked her other photos (loved the idea of shoe on hand—note a German pun there), and found that she's even more beautiful here than on her other images. I think it is a certain level of retouch, but it is moderate: there are birthmarks slight and barely visible sports here and there, and they let the face live. (I have the suspicion of a good amount of blur on the skin, even a bit overdone, since no pores are visible. A very slightly less would be a lot more more. The treatment around her eyes are really gentle and beautiful, wouldn't notice without the other pictures. Or it also goes the account of the light or make-up.)
About the lighting: by the catch-light I suspect a single octabox overhead, 30° to the left. I am really curious what did you used more? The lit area is so narrow, fall-off is so smooth that I would guess a honeycomb or something... It is not a beauty dish, that would make sharper edges... I am really guessing, I am learning about the lights, and testing my knowledge. Would you tell me?
Oh, and I didn't mention her well coloured lips and her expression of... waiting? Asking? Her look goes extremely well to this light!
Nagyon szívesen! We can change to Hungarian if you prefer to practice.
Meanwhile I downloaded the preview to see it with neutral background. With black surroundings all the issues about hairlight and skin retouch are gone, they are just not apparent with dA's coloured backings. I'd make a different skin retouch with slightly different result, but that is not better or worse, but only different a bit. For this image your way of retouch suits very well, if you take a look on black backdrop. Worth to give a try, it shows a way more of this image's most valued features!
