Certainly imposing and well framed for effect, and it certainly speaks authority to me. Perhaps it doesn't move me over a certain point, perhaps slightly intimidates me.
At first glance I thought this was fairly impressive but on closer inspection, the image is terribly pixellated over the sky and near the bottom. I'm not sure what processing you did or what compression you saved at but the image has really suffered for it.
JPEG compression artifacts are visible everywhere in this shot. You've got a good file size of almost 300k, so I would guess it may have been saved with high compression somewhere else along the way.
