Oz - stone column

did i spell column right?

This is a quick landscape rendering that goes with the other "oz" pieces ive done. see heres the idea...

you splash into the ocean, sink about 100 or more feet (hasnt been established yet) then you hit this upsidedown surface and fall through the air to another surface. so when u look up at the sky, its a body of water... not the sky.

im having problems visualizing it. and these definatly need more work. anyways, this one was sketched in Painter, and detailed in photoshop.
