I'm not thrilled with the processing here; the focus is a little soft. The vignette effect was slightly enhanced in post-processing, but mostly natural, as the sun was reflecting off the sign behind her.
This is near the contruction site of new high rise development and the sign behind her is advertising it. I like the juxtaposition of old and new things here.
This really has a journalistic feel to it, at first I thought she was a protester. I really like the B&W and angle you shot this from. I wonder how it would look with a bit cropped off the top to make you subject a bit more prominent.
