The first picture is taken of some Samoosa's on a decorative Mexican plate, to enhance the colours.
The collage is a mix of various snacks for that party you are about to hold!
Display is also half the enjoyment when eating your snacks. It is like the framing of a work of art. It can make or break your picture.
