One definition of collage is "a technique of composing a work of art by pasting on a single surface various materials not normally associated with one another..."
The background is one my own textures. The individual components are comprised of clip art butterflies and a hand, assorted brushes, self-portrait, Photoshop Elements shapes. Topped off with the "DreamWonder" texture.
