Wow, an amazing look for 3D. Would love to see your SBS before I vote. Good luck.

You haven't included in your SBS how you textured your objects to achieve the painterly look of this render. The material on Charon's arm also seems to have a mapping issue.

Hi Mad, yes you are right that the arm of Charon has a mapping issue, only I accepted this. When I solved the mapping problem of Charon became less appealing.
The painterly look of the background is achieved by adding the a terrain and slide this partly underneath the plane surface. This infinite plane has a multi channel shader with a blue transparent color and a waves bump setting. The waves amplitude & frequency setting is very low. In this way the shadow of the boat smoothly interacts with terrain underneath the water surface.
In the background there is a fog, in this fog I placed my transparent ghosts figures. I wanted to have my ghosts and the fog gently compete with each other to attract some the attention.
The clothing is a multi channel color shader with a bump texture setting.
The skin is a multi channel mixer with a blender value setting.
I will add the texture settings later this evening.
