not keen on the lighting. Compositionally, the image is a bit.. blah. Looks to me like your model (you) are a very expressive person, you should have just let some of that natural expression come across on the face, it would have done wonders for this image.
Between your eyes, your hair, and your looks in general you have alot of good things to work with. i think the white background is just washing you out however.
Ah... very nice. It could be much better with two things changed. If you'd take the photo bit farther from the wall, make the shadow little bit blur, and if you'd do better post process, like contrast, and maybe noise reduction... Try and let us see after the challenge is over if you want :) Overall very nice photo though :)
nice eyes and face - really well done here - but the harsh shadows behind you and the harsh lighting don't really help - softer lighting would accentuate the great features you have
Your lighting is a bit harsh. This makes your features appear quite flat and creates the shadow line below your chin which doesn't add to the impact of the shot.
