Main Street slightly repainted

There was something that always bugged me after I thought that I had finished "Main Street". One was the whole painting looked a bit pallid and a bit too "real" so I gave it a thin glaze of transparent yellow but this still wasn't enough so I gave it another glaze today which has brought it to a state that I am now happy with. I also accentuated the Cold War era feeling that I am interested in by having a vapour trail high in the sky.
