Brilliant portrait!! I love the depth of field along with her pose and gaze. Just an observation, I would crop just to the inside of the triangle of light on the upper right hand side of the portrait and just to the inside of the rectangle of light on the upper left side. This would remove the truck to the left yet, still keep plenty of the railling to the right for depth. The model would be slightly off set to the right of center as well. The viewer would be more in tune with her perfect gaze and pose.
thanks for in depth comment. generally i couldn't crop because of layout needs. as you have said it is true that a little cropping can make this picture "simpler" and with less disturbances but as most of commercial work you don't have to much time to think. Nevertheless a good pic is a good pic and bad one is bad one and it is my problem to do good pic with time restrictions but reality is reality. you are right with cropping but truly this truck wasn't a big problem for me then and taking under all circumstances i thought that it is not a problem.
