Zanshin translates as remaining mind or lingering awareness. Technically it means: after delivering a technique your body, eyes, and intention remain focused on the opponent rather than relaxing or looking away. Common zanshin failures I see in your match footage analysis: lowering the guard hand immediately after a punch lands, turning the head away before completing the follow-through, and breaking stance early to walk back to your start position. The practical fix is to hold your full technique position for one second after delivery — guard up, eyes on target, hips set. Your sensei has noticed something real. In your last 3 logged tournament matches, your reaction time after scoring dropped significantly, which suggests you are mentally finishing the match before it actually ends.
