FYI, when I say "straight", this is the alternative that I'm distinguishing from. There are many example of the railing curving out, usually at the bottom like this, but I don't think we'd want that, right?
This exterior balcony doesn't use shape very well in the formation/structure. This balcony/porch has way too many curved and circular shaped elements to it. It would be better if it used squares, rectangles, triangles, and even odd lookin shapes that don't have a deffinate name.
