The dots, diagonal lines on the right, and most likely the text on the left are all brushes, and maybe some of the designs in the middle, too. The grainy/glow-y/paleness is a difuse glow, and the coloring is probably a texture. Whoever made it might have used an Accented Edges filter on the pics, as well.
At least, that's what it looks like to me... I'm probably wrong
