Here is the Stay Puff Marshmallow Man and the Phantom Manor in the display with lighting effects.
There is a black light in front of the whole display, some color changing lights on the sides (lighting StayPuff green on the left at the moment) and some practical street lights. You can see two street lights above the entrance gate to the Phantom Manor in the back. It really all comes down to the lighting, although I put a lot of time and effort into the models for my displays, even basic models and toys look great with good lighting.
