#1 and #3 are the same but with different processing, yes?
#1 - First thing I noticed were the eyelashes on the far eye. You are neither in a 2/3 mask or profile mask. This hurts. The strangly hair on the far side is another setback. While you have created a strong line with your model's left arm, the positon (AND THE COLOR) of her hands is a total miss IMO. Then there is that sting of lights extruding from here nose in the vacant top left of the image.
#2 - This is a good example of a 2/3 mask. both eyes can be seen and the nose is not breaking the far cheek line. I think you have created some good lines in this image, but a couple of points to mention. First is having the thigh pretty much square with the lens. Although she looks extremely fit, this is a no-no because it enlarges that size of her thigh for the viewer. This is further accentuated by having the far leg so close to parallel with the near leg (look at the kneecaps). The near hand is in a more masculine position by being broad to the lens and the far hand is truncated. Again, keep a check on the straggled hairs. With the conversion, the blacks seem awfully black.
Thanks for sharing.
