Theres not much to critique. Its pretty good for a beginner. Just keep practicing. I like to stay on the ball of my foot (my lead leg) when throwing kicks, especially back to back rapid fire kicks. I get more power out of it and it helps my balance. Check your stationary lead leg on your double kicks and notice your foot is not pivoting. Thats a error everybody makes when they first start. Usually you will notice this when your kicking the thai pads for multiple rapid fire kicks and your falling off balance or your not getting the power that your first kick had. Easy adjustment.
