I notice you're not fully pivoted or turning the body over for the kick. In JKD we would call this a snappy hook kick. But there is a version where we fully turn the body and commit, but still fast and bring it back. What many people don't know is a good kick doesn't take much power to KO someone. Kicks are much stronger than punches. If anything, try playing around with the fully committed kick as well. You look definitely fluid and fast! You can do a full mid and straddle split?
