Creating a movie poster

This is my first attempt (without cropped models inside). The theme of this movie poster is horror-comedy. Although we see no comedy in this. It looks abit dull and gloomy. Dull and gloomy comes together with horrow but I thought theres no comedy in this. So I decided to make a new one.

Movie is about 4 stereotypicals with mutual interests,
that is to survive an apocalypse!
