NB: Visuals aren't final. There are lots of things to change and tweaks to made before final rendering. Consider these images as just a rough indication of how the final shot will look.
I've was a bit unhappy with certain aspects of the renders. As I've never done this sort of thing before, the process has been very trial and error. Sometimes I think I've found something that works, but on another scene I discover something new and then have the desire to go back to the other scenes and alter the lighting and materials with these new ideas and processes. Here's the latest batch of test shots, with a few more to come soon. Some work better than others but hopefully now you can really get a feel for the visual style.
