Looks like you're taking an extra step with your lead foot when doing a left body kick compared to a left low kick. That extra bounce with the lead foot gives away the kick, and if your opponent picks up on the pattern he'll know exactly when you're throwing a low kick or body kick with your lead leg. That would be a bad thing. Try to throw your left body kick with the same footwork as your left low kick; step with the right leg to set the distance & angle and throw the left kick, don't do that little bounce step with the left foot before moving your right leg into position.
