The Mall in Central Park

 

This is The Mall in Central Park, NYC, near the Literary Walk area if you are familiar with it.  It is quite a nice place to take a stroll, with the beautiful elm trees and their shady canopy.  You can see some slight ghosting on the right side of the frame - that was a bicyclist cruising by.  This was a single frame shot, long exposure, about 20 seconds.  Originally I had this all bright green since this was taken in early summer, but once I converted it to B&W I decided that I preferred this look.  Your feedback is appreciated.  Do you like the B&W look?  What would you have done differently?
