I recognized the building in the foreground and realized, after a bit of google street view, that this is the intersection of Kanunu St. and Amana St. facing somewhat in the southeast direction. This is also a few blocks away from Ala Moana shopping center and across the street from the Pagoda hotel.
Beautiful job! Thank you for posting the work pictures as well. I'm always curious to see the process people use to color digital images. Everyone seems to have their own personal set of steps. Very good work!
