Starting a Sci Fi Scene

Here is a start to a Sci Fi scene that I plan to do in UDK. I plan on creating a layout of a small-to-medium sized ship, and then creating the inside. The ship that I am thinking of trying to make is going to be a small cargo ship. These are the start of two of the environmental pieces. The tall, skinny piece is going to be a pillar, I plan on making several variants of the pillar. The other piece is a wall piece. As with the pillar I plan on having multiple variants.
