The first thing that stands out is your absolute consitancy! Your overall position looks great. You are a little less confident looking on Chick, I see a little pinching at the knee, but if she was being a nix, this may be you riding defensively.
Emerald- her release isn't really that bad.... just... Huntery. LOL If you look through the photos, the horses are not gaping at the mouth and in the last pic she adjusted and gave more as the horse reached.
Your crouched over a low release, where I think at your level you could easily do an automatic and create a nicer line and feel. I'm wondering if this would lessen the mild hunch I see in your back. To me you just look bundled up right at the whithers.
If your horse says no, you either asked the wrong question or asked the question wrong
And God took a handful of southerly wind, blew His breath over it and created the horse
