Hard to tell in slow motion, but looks like you are taking too long to setup and remaining static for too long and you also never address the target while barely turning your shoulders back.
I'd suggest working on perpetual motion drills like Double Dragon, Standstill Figure 8, and Elephant Walk. Also Whips Step, Reverse Stride, and Door Frame/Bow Arrow Drills. Let's get you moving around more dynamic and fluid, instead of being so cautious and stiff.
