Some of the aspects of the pictures could be cut around, like a person sitting in a window, leave the person, cut around him, leave the curtains if there are any, put gold cellophane behind that so it looks like the house lights are on behind him... You could fix a light to spotlight on the bear...add some opalescent glittery paint to the snow around him....
There are so many different ways of doing these type of pictures :D:D:D
