While I appreciate that your steady hands are working, I doubt that you will be able to hold that steady shot for a long time.
Look at that crowd, think about the duration, the shot, the angle of viewing.

In fact, many of the field PIOs use tripods/monopods for daily use.
And no, with my setup, you don’t even have to argue about vertical or horizontal.
