Both feet are square to plate, toes pointed slightly in. Pressure on the inside of knees. Note the relaxed grip, “knocking knuckles” aligned.

Lower body: This batter has already loaded from leg lift into stride ("toe touch"). Front foot is in a closed position (ankle leads towards pitcher, not toe). The front heel is slightly up. She stays tall, shoulders and hips square to plate. 

Upper body: Hands are high & close to her body at separation, as if a rubber band stretches from hands to front foot.

At the point of contact ("barrel to ball"), this batter's elbows are slightly bent, like the frame of a house / “power L”, still in the palm up, palm down position. Bat angle corresponds to location of pitch. Her face is tracking down on the ball.
