Rough Plans around a Tree

Some really rough sketches/plans for the layout of my scene.

 I like the idea of a Tree growing over the ship, to illustrate it's been there so long, so the idea of the roots covering a door also allows the option of leading to an entrance to the rest of the ship (if it were a level), and at least makes it seem there's a way out or way in etc.

I roughly layer out my idea in Unity to have an awareness of space (this is then edited on photoshop). There are basically 3 main pieces to the set, a tree, the statue and the relic of the ship. There then will be additional pieces of debris, such as cogs, planks of wood/metal etc.
