Shading and Lighting Update...

The main part i am currently indecisive about is whether to retain the shadow from the light casing in the boat cabin scene. If i retain it, it will increase the drama as the boat moves and the shadow moves with it. A positive offset will be the decrease in movement i have to apply to the cabin which will in turn allow the dynamic to work more effectively. The negative for keeping them is the loss of clarity, which will obviously be gained if i remove them. However, this may result in less drama, and thus more exaggerated movement applied to the boats rotation.
