This type of painting is quite easy to do, if you have a photo that you think would suit. You start with a photo like this: (This may not be the exact photo that I started with, but I can't seem to find that one!)

Then you open it in Photoshop and apply a "stamp" filter (found under "Filters" and "Sketch")

Then I just used black acrylic paint to "copy" it onto the canvas. It's hard to get the proportions right, and I definitely didn't do too well, but you could always print out the adjusted image and trace it onto the canvas instead of drawing it freehand.
