Drive In

This seemed like a really good idea to me, and since nobody else is doing it (I think) I thought I might as well give it a shot. Here is the .gif file, everything is on seperate layers in the .psd so i can make changes, so please give me suggestions. I plan on adding something to the screen, putting in a projector, adding lines for parking spots, and adding a few cars. I just wanted to see what people thought of the idea and then base the plot on their opinions. Also it seems like a lot of people are getting more detail into their plots then I am. I might be imagining it, but if I am not could someone please tell me how I could do this?
