#1 - Where has the collar line of her top gone? The catchlights indicate that your main is in a less than optimum position, It also is a tell by the nose shadow. What happened to the definition on the right side (CL) of her nose?
#2 - What I see is that you have exposed the ambient nicely and exposed the subject well, but with some ambiguities. I think I read you had one light, an SB700. So riddle me this. By all intents and purposes, the ambient light appears to be in the PM and more closely to have the sun already set below the horizon. So in my mind, this eliminates the sun from being a direct light source. In her right eye, ther are two catchlights, camera left and camera right. Her nose shadow has a light source coming from camera right. The shadow cast by her earing is coming from camera left. The shadow under hep lip seems to be coming from above. There are two definite light sources as indicated from the reflection off her nose. I can't go on, I'm perplexed. How have you lit #2?
