Compositing Progress

For the compositing unit so far I've set up a few scenes using photos from my holiday in Turkey. 

First I set up the floor and sky planes and used the compositing tags to get the perspective of my shapes and the lighting right.

For now I've just set up a cube to get a feel for how my animation will eventually look on the background itself. Here are some shots to show the settings and tags applied to the materials/planes.

          

                            

 My second one is a similar scene but with different lighting and perspective.

Before I make any decisions regarding the animation I'll be sketching some designs for what might suit the scenery. I'm thinking ice or glass blocks for the second one, and perhaps something organic and fluid for the first- maybe tentacles or even plants?
