The casts are my models and everything else done by much talented artists. I've always wondered if the 3d stuff qualifies as art as you arrange things and then take a "snap". The real art is drawing all of it from nothing. The final outcome is an image so maybe it is art and probably takes as long?
The thing about these things is what shows up in the final image. It wasn't until I viewed the final result I noticed the shadows though they really make the render as far as I can see.
