A ten yard shot from an elevated position creates one hell of an angle to shoot a deer at!! You most likely got the back of her shoulder blade. My suggestions are..
1. Aim at the hair line on those close shots. They're going to react no matter how close/far they are. If you aim low, they'll duck into the shot and it will hit them above the hair line and below the shoulder blade shredding both lungs. You'll find the deer within 50 yards.
2. If you can, let the deer get 15-20 yards out to increase you angle at the body. This way, you have more body to shoot at thus increasing your margin of error.
