The term Tilt-Shifting actually has a different meaning than the Tilt I am referring to. There are "Tilt-Shift" lenses that are designed to straighten distortions of converging lines when you look at something like a building that has straight lines. When ever you tilt your lens upwards at a building, the top of the building will look much smaller than the bottom, but if you use a Tilt-Shift lens you can make the building have parallel lines.
Thank you for your compliments on the fight poses. I use real movement during my fight photos. I find still poses usually look fake, especially if hair and costume should look like they are moving.
As you said, I think the camera tilt did add some depth, as it included more height to the background of the glass buildings, and more foreground to the floor. Great observation!
