Hobby Terrain: Sci-Fi Storage Units

One of my all time favorite games is Sci-Fi. I grew up playing a home made game that to this day is still one of my favorites. Might be due to the fact of all of the memories. So now I have purchased some figs to start painting and I have also started on some terrain. Here are some silo type structures that will hopefully add some flare to my board.
Cheers,
John...
