This feels so different from the rest of the pieces you've made. A lot of it has to do with the urban setting; even though you still have plenty of symbolism and/or blatant symbols here, the cityscape makes it all feel dirtier than usual, somehow more artificial, even the symbols themselves. I do like the fact that you still have a shadow of something natural, that tree, even if it's just been made by the pollutants running down the wall.
The blue door....it's the brightest spot in the picture, and even though it logically looks like there's nothing behind it, and that's just a wall, its brightness gives me hope that maybe there is something? And then the lion changes the context of the scene too.
