The background in the mirror was replaced with a new partial rendering.
The fur was rendered separately and needed a lot of editing until it was matching the lighting of the scene.
This manually drawn layer was used to create the steamy and dirty feeling on the mirror.
The image was partially darkened, especially towards the outer areas, to create a more focussed and suspenseful mood.
This layer with a diagonal gradient was used to create an overall colour scheme of warm and cold colours.
These areas were manually blurred. The depth of field was created manually to create a more individual and intuitive focus.
In order to create a Sunday morning mood these lens flares were partially blended into the image.
Cracks were extracted from photos and mixed into certain parts of the image to break up the digital regularity of the wall and tiles.
Many layers of manually brushed colour, luminance or blur corrections were used to lead the viewers focus into certain directions. Logic and realism are sometimes less important then the overall mood and focussing of a composition.
Pieces of 2D textures were partially blended to add more detail to the materials. This could have been done also with better materials in 3ds max, but when you are creating a single still image instead of an animation it sometimes brings more freedom to do it this way.
