To be honest, I dislike light effect scripts. While they do make it easier to toss in effects with ease, the misty or bloom style of lighting they provide irritates me. It always makes me ask : "Boy, is it misty in this town or something?"

( Actual Night Lighting )
Also, unless there is a full moon, there will not be shadows as are currently displayed on that map. In fact, they would be different than before due to the different angles of light sources. Most tilesets are configured for sunny environments as well, and that can work heavily against trying to make a nighttime scene, even with proper lighting.
Anyway, I'm aiming heavily towards realism and slightly nit-picking, so I'll hush up and leave off by saying that there are other ways to offer lighting for your scene. You could easily have light streaming out from the windows of the house, as the windows should be lit. A little bit of blur and perhaps illuminate a bit of the ground and there you go.
