Hello, I have just submitted my picture! Thought I'd share my 3D workspace (in Blender) as well, sometimes it feels even more theatrical and fun than the final picture I manage to wring out of it.

You can see it is VERY tailored to the drawn composition... things stop working / break apart / go missing with even the slightest camera shift. But that's the most fun bit in composing based on a 2D-drawing ;)
