I heard of this visual assignment, Fat Cats Make Art Better today in the Google Hangout.  It sounded fun, so I looked for two CC images in Flickr and pulled them both into Photoshop.  I resized the cat image to get it closer in size to the Ophelia image.  I used the lasso tool to cut out the cat and place it on the Ophelia image and then used to clone tool to blend the cat into the foliage.
