OK, so a lead leg side kick is much harder to critique the chamber, particularly when done to the side (from the camera's POV). A rear leg side kick towards the camera or if you're kicking right leg, towards the right edge of the video is better.
However, as you asked, I paused the video in YouTube, hit "," multiple times until at the beginning and the hit "." 32 times. That gets you to a point where the kick is extending to the target. It appears that your kicking foot is past the line formed from your hip to the target (i.e. out to your right hand side), that means the kick force is moving slightly to your left as you extend, whereas usually in a side kick it would go from the left to the right slightly.
Again though, not the best angle or kick style to ask for tip/critique on. A skipping side kick (I would call it that rather than a lead leg side kick, which would normally be just a lift and kick, without the back foot moving) is easier to perform than a regular side kick, because your body is already turned to the correct angle and the skipping of the back/standing legs makes it easier to pivot it.
