I hadn't noticed the technical critiques but I see them now, but don't find them objectionable. I find the form resembles a suspended acorn. It also conjures images of an alien spacecraft. There's a lot to look at here. This appears to be a many-step process to put this all together. I lingered a long time which is what I want from the observer out of anything I create. I think it's perfect for the show.
The only (very minor) critique I might make is that my eye wants the finial to terminate in more of a point at the top.
