I will say that the model's hair stands out very well, this wouldn't have worked nearly as well with a lighter hair color. Secondly, because her hair does so, it thus draws our attention to her face and giga-watt smile. Very good, that. Then the styling of her hair guides our eyes down along with her arm. We than see the image in a complete fashion.
The lighting on this is also most important. Had the background tiles been lit in a stronger fashion, it would have overwhelmed the focus of the photograph. You've kept the lighting soft on the background and direct on the model. Again, very good.
Hi! I hope you don't mind but I featured this photo in my "Monday feature" journal. It would be cool if you went over there & favourite it & look at the other artists' work! Thank you, & have a nice day!
