I'd learn your pulley rein stop. Don't run her until you are comfortable she won't bolt. If you're holding onto the horn, what're you going to steer with? :P Work on walk-trot and getting her to stop and downward transition. It's quite dangerous for a new rider to be on a quick horse without a good stop, especially one trained to go FAST and turn on a dime. My bashed hip is proof that it doesn't end well!
On the plus side, your heel does look good, but it looks like your entire lower leg was off of her? I'm a knee-gripper, too. :P
Glad to hear you have people willing to help you-- it's essential for every rider's safety and progress to have eyes on the ground.
