The technical bits of riding are sometimes based on a particular sport. For example, a dressage seat is best on a collected horse, and a forward seat best on a forward balanced horse. OTOH, if the horse is likely to make sudden, hard stops without asking permission first - which would get one huge downgrades in a show but which was & is a part of my riding life - then heels forward and down can save a spill.
Riding with constant contact is fine. I have nothing against it. It just isn't the normal goal in western riding. And for those who ride bitless, as I used to do, 'contact' takes on a whole different meaning.
From a western riding perspective, the thing that bothers me about this:
is that it looks tense. I hold my reins between my thumb and index finger. They support the weight of the rein. My other fingers get involved if I need to take the slack out, or to give cues with my pinkies - and with my right hand, I have to move my pinkie up to use it.
If the horse gets excited, then things change. If the horse won't respond to my pinkie, then my fist might be used. Or my shoulders. Or my whole body, if that is what it takes. But most of the time, my horse feels the change in how much slack is in the rein and responds off of that.
I prefer the look of the OP's hands, which look relaxed to me. Riding with constant contact is one of those places where English and Western riding diverge.
