It is a nice perspective, and I do enjoy vanishing lines in images, but I'd suggest going back and positioning the camera directly in the middle of the boardwalk so the posts on the sides create a perfect mirror. Then, if it's sunny, shoot one photo at about 10:30 am and another at about 1:30 pm. If this bridge runs north to south, even better. Clipping half of one photo and placing it over the other photograph would give you shadows coming from both sides, a surreal portrait of our world if we had two suns. If you can leave your tripod in the same place for 3 hours you would get a perfect match--persistence and patience always awards great imagery. You could also mask out both shadowed sides and place them over a photo of a distant, dramatic sky. THAT would really be surreal.
