After posing the characters I sculpted some folds for the clothes, boots and gloves. Also I refined the Emperor's head and added some scales. I use Pixar's sub-d and sculpted with multi-resolution. To do this you must convert your model to Pixar sub-d by pressing Shift + Tab. You can enable multi-resolution in the sculpt tools (Fig.15).
When I finished sculpting an item I set the current level on multi-resolution to 1 to have better performance. This meant I could sculpt many items without slowing down (Fig.16).
Lights > Rendering
To light the scene I used five area lights and an environment material with four color gradients at low intensity (Fig.17).
For reflections I made some big planes from right, left and above (Fig.18).
I rendered three passes (Final Color, AO, SurfaceID) at 5025 x 6000 pixels (Fig.19).
