I thought you might appreciate seeing how I personally have been putting the tutorials that I found to good use. I've already shown you the image I created using the layering technique. These three images were all created using the other tutorials I'd found and posted. They were easy to make, and the longest that any of them took to render was a little over 5 hours. Now, granted there are other ways to create these same effects. I'd love to see what you can come up with!
