Note the old exercise precept: “The body follows the eyes.” When overhead squatting, it’s important to keep a stable & upright position. You can’t do that when looking at the ground. In any case, the ground isn’t the goal. Keep the torso from dropping forward by keeping your head neutral and your gaze forward or slightly up. Pick a spot on the wall, and stare.
WHITE-ORANGE should keep weight light and just work on becoming more familiar with OH Squatting. BLUE-PURPLE+ may push the weight, but only as technique allows.
