Cow Collage

I made this collage using this tutorial http://www.photoshopessentials.com/photo-effects/collage-warp/. The only thing I would add to the tutorial is that when you make a copy of your warped photo and fill it with black, you'll want to make sure your fill is set to "Preserve Transparency". To do this, instead of using the shortcut, just use Edit > Fill and click the "Preserve Transparency" box. This is so that the fill doesn't fill your entire layer, but just the non-transparent parts.
