Here's another fun tutorial to help you stretch and grow. This is my version, and I actually did it twice. The first time I followed the steps exactly and the result was not like the sample. The second time I changed some of the layer blending modes to get closer to the example. Give it a try - it was not all that difficult! I'll use the techniques I learned, for sure.
