So Artful Challenge-Harlequin B/W Collage

I just completed this collage.  I had to learn some new things with Photoshop to do the simplest tasks, like draw a line.  In researching the topic I learned that there are many living things with the title of Harlequin.  The Harlequin Sweetlips  is also called a clown fish.  The flowers growing voluntarily in my driveway are Harlequin flowers.  I never could remember the scientific name but I think this one will stick.
