1) The angle between the forearm and racket shaft at impact is too small for a kick serve. There is no upward movement of the racket head during impact. The video shows that.
2) The ball does not bounce up to the right as a kick serve should. I believe that requires that the racket face be closed by about 15 degrees at impact.
To understand why the ball bounces to the right for the Kick serve, imagine the court touching the bottom of the ball as shown in the picture below. Next imagine how the felt on the bottom of the ball is moving just before first touch. The bounce will be to the right (of the X axis (forward). The slice and flat serves will have the felt that first touches much closer to their spin axes, resulting in much less sideways bounce. Last, now imagine where you would contact the ball with the racket strings to give it the spin axes for kick, slice and flat serves as shown. Note, the actual contact spot and ball-string distortions should be determined by high speed videos because of impact distortions.
Measured spin axes for the Flat, Slice and Kick serves. The lengths of the arrows are proportional to spin rates. The Kick serve is spinning the fastest and has the largest spin axis tilt.
Your serve seems to be very good with a high bounce. The bounce has no side component. The winter 'bubble' backstop may have a shorter than normal back wall that makes the bounce appear higher than usual. ?
The motion blur is very good for indoor lighting. What camera/smartphone?
