I finally decided to make an effort in participating this weekend, but by the looks of things I won’t be able to finish before time is up. Regardless, I still intend to finish this someday. The only research I really did on the subject was a google image search, so this probably won’t be very accurate (and doesn’t intend to be). So anyways, any C&C is greatly appreciated. 
I love these columns. They look great. Now you just need to add them to a scene
