Here's a second render, with just a little depth of field. I like the rich red color as it sets off the bright mtealic highlights. It's amazing how just changing the floor can alter the whole feel of an image.

As for making a tutorial, I'd love to, and will some day. Problem is, I looked into what it would cost to get all the software I'd need to do it, and it was around $1000 to actually start producing DVD's, which for now is out of my price range. I'd want to do a video tutorial as it just takes way too long to explain steps in writing, and also it just gets confusing for the person who is doing the tutorial.
