It looks really good in my very narrow entry. When I got the fixture out of the box, I felt overwhelmed due to the amount of pieces. 
We mounted the metal part to ceiling first, then the glass pieces went on while the base was in the ceiling.  All of the glass piece were in a styrofoam insert, inside the box. The are different size glass pieces, so be mindful when you are putting it together that the longer ones go in the center. 
All in all, it took about 40 mins to install.
