Learning cinema

I've been applying myself during down time and learning Cinema 4D. I've been following the introductory tutorials at http://greyscalegorilla.com/intro-to-cinema-4d. Currently I've finished the lesson tutorials and moved on to the project ones. I feel they start out dry (as things tend to be when learning what tools do) and becomes much more fun as you apply what you've learned. Now that I jumped into the project I'm completely addicted. Here is an image capture of my progress so far.
