I think the contrast is pushed to far here. I think more more light or longer exposure during the shot might have been better, but then again I dont know a lot about lighting.
The composition is nice. I did a photo like this once, but she was looking straight in the camera. I didnt come up with a different angle like this one which I find really inateresting.
Hi Sewen. An eye-catching thumbnail image that was not supported by the full size image. If you need comments then it is helpful to give some information about your intentions, the equipment, film and lighting and so on. This image is intriguing in the crop and the fact that the model is not looking at the camera. The tonal range is compressed and that is fine if you wanted to go for a high key treatment. The details in the highlight areas on the face are largely missing. The hair shows a lot of white spots that is either a scan or a hair problem. The shape of the model's left ear that the hair has draped over on the right of the picture is disturbingly unnatural looking and not very flattering at all. I would be interested to see this one redone if you could shoot it again. Keep shooting!
