not bad at all. your not kicking with your foot, but the kicks still look to be landing too low on your leg for my liking. Seemed you were kicking more with the lower shin/ankle area. If you want to kick with lower shin thats fine, but no ankle. Some people prefer lower shin kicks, because it gives you a bit of reach, which is why most beginners naturally tend to gravitate towards that way. I prefer kicking with mid shin, or even slightly higher. Leg kicks are easier to learn than mid/high kicks as its much easier to turn your hips over and get full rotation low, than it is high. specifically for people that are limitied on flexiblity.
