I think you need to start over with the lights as it looks like you blocked yourself by playing to much and only with the lights and colors.
Save a copy of the scene, remove all the lights and start over, if not just to see how a fresh start can improve the lightning.
I really like the scene itself but the lights and colors are no where on the same levels. I don't like the pink tinting I think that should be rather something like post effect or later as variation. For the rendering itself I would stick to what you are used to see in real life, so perhaps a blue sky bouncing light rays on the top of the roofs, and perhaps some warm and bright light / shadow play with slight variations of orange on bleeding spots.
Just some piv I google image searched:
it also has that vintage look you are probably after but the colors do not shift so crazy in one direction. It is still quite well balanced with the browns, yellows, greens and many other colors.
