step 1 ; first I built a tunnel by adding 8 cylinders together.
step 2 of 4
then I welded them together.
step 3 of 4
then I added the ocean, adjusting the level so that only about a 1/3 of the top of it showed inside the tunnel.
step 4 of 4
then I added one of my personal cloud images to the background, adjusted the lighting & textures, and then rendered several test renders til I got it to this stage..
