AWESOME designs - kudos to the architects! I agree that it's hard to delineate between walkway and road - is it easier in color?
On the ground it's easier. There's an obvious curb everywhere except this intersection. The street doesn't go anywhere, so there isn't much traffic, so in practical terms, the whole area is more of a big plaza.
I love street scenes with patterns. You don't know where the road ends and the sidewalk begins with this one. This looks like a great place to definitely shoot street shots.
