I created some sky and clouds to give a dark and gothic feel to the outside of the church. I am very pleased with how they look as it does work well with the scene and they look just how I wanted them to.
Here below is a picture of the sky and clouds in the scene that I am using at the moment
This is a picture of the clouds from high up. This position is being used in the animation that I am doing for the assignment. A clip is shown on the section called 'My Playblast'
Here is the gothic look created (but lighting isn't added yet)
