Colour popping

I planned to try the colour popping technique using adjustment layers in PS and thought this night scene could be much more interesting with a bit of pop! I took the shot of Maria Kyrka on Södermalm in September. I've converted it to B/W and brought back some colour in the church as well as regions of light and reflection such as some windows, the street lamp and cobblestone. The shot original is beneath the edit one.
