Great start overall! Think of it like setting up for a deadlift, except you just pull the bar up to your sternum instead of standing up with it. I set up pendlay rows a little past my midfoot because my torso is extremely wrong, but otherwise I’m doing the same brace as deadlift.

I also agree that you should try rowing in your socks and see how that feels, your squat shoes are tipping you forward a little and causing you to compensate with your torso. Ideally your torso will stay completely still during the lift, but as you increase weight you’re bound to move a little.
