This was done from the staircase of the High Block of Hong Kong City Hall. There is air condition, and no one really cared about me sitting on the stairs. What a nice place to sketch in a hot summer!
I wanted to do the trees better, which was why I chose that spot, but the security guards didn't allow me to stay on the bridge. The sketch was done in about 20 minutes, the shortest record so far, and my eyes kept on moving around to spot the guards.
