Over the sholder look near the stream (Portrait)

The light is coming off a stream. How can i make my photographs more

dynamic?? Thanks in advance

I really like the mood of this photograph. The lights and shadows projected to the model's skin tells about leaves being excited by some soft breeze. Although it's difficult to tell whether the shadows were placed in purpose at their current composition, I think is good the relative bright of the upper arm, and the faded shadows at the waist area. What doesn't look good is the model's lips color; looks like whitened by the left corner of them.

The picture is warm and says a lot about the sorrounding nature.
