Blockout

I am happy with the block out now.  I have added the landing platform and the lookout tower.  I decided to move the tower up onto a higher vantage point.  It didn't seem practical having it low down and it also draws the eye across the scene.  I have added more rock face and put another door into the prison. I wanted to give the impression that there was more going on inside the rock face. By adding the second door and short walkway it implies there that the prison is much larger inside the cliff.

I still need to block out the landed ship on the platform and the lifting arm mechanism that will lower the edge parts of the landing platform.  I am really hoping to get some nice light coming out of the two slit windows running along the cliff face.
