Thank you for teaching this amazing layer style. I never knew the importance of global light before and about moving the shadow around independently. I have created similar effects in the past using the warp tool, but this is so much easier. :-)
For my project, I created this maple leaf shape using the pen tool to trace over my hand drawn image. I created the cloud by using the same circle technique as you taught but I merged the shapes together.
I also added some text in the mix and put every word on a separate layer since each one represents a separate piece of paper and curls independent of the others.
