A lot of that i'd not thought of in terms of symmetry. I'm going to meditate on that this-afternoon while i'm working on the (both necessarily AND unintentionally asymmetrical) house i'm building at the end of the garden. I seek out and shoot a lot of 'juxtapositionings of disparate elements' or incongruities, and these have strong echoes in your broad use of the notion of asymmetry. BTW - loved the Wildebeest shot... the dwarfing of all by Africa's 'Big Sky'. The Calgary building, too - the only thing that spoiled that for me is that i lived in Calgary for six years and it's a chapter in my life that i try hard not to remember! All the very best and thank you for posting.

Great video and an interesting view. I like symmetry and asymmetry both. But for me mostly it is by visual elements, as that's what I was taught during my college days in architecture school. The picture with big and small planes is a great one. It shows asymmetry while being balanced due to the size of the area occupied by the sky against the big plane. It even gives the impression of a rhythm, one would expect another plane behind but far away out of the photo frame. For the last two pictures, I personally would still call them perfect examples of asymmetric composition, because of the visual elements (animal head at center, but body at left. Also the curve and top edge of the building shot at that angle, and placed on one side in front of the many vertical elements). But I would call the other aspects of those 2 photos as contrast (life - lifeless background , Old building - new one).

Certainly, assymmetry is one of the simplest ways for the artist to introduce movement in a picture, which is specially valuable when the subject is an inanimate object (the picture in 1:14 is gorgeous). It makes the viewer to think twice why the photographer introduced that imbalance and what he wanted us to think about or pay attention to.
