Its very creative but you emphasize too much on the same light npcs and too many of them. Try something new like this: lighten up the area a little more not too much i think alot of people just have their screen brightness down, script the npc lights so that only one of them is on at a time and when one goes off a few random seconds later another one comes on to show that someone might be moving around in the house
or have them all turn on and off randomly every few minutes to show that there are people in the house. Thats just a suggestion. Also it seems a few lights were randomly placed remove some of them too many bubble lights around. Fix the choppy grass to dirt tiles they are generated so you need to fiddle around with them to make them look a little better.
